Appearance
A deep hole drilling engineer who relies only on experience will eventually hit a ceiling that theory alone can break through. But with no single textbook covering the full breadth of the field — from BTA tool design to drill-string dynamics to coolant filtration — knowing where to start is itself a skill.
Deep hole drilling is a specialised field within manufacturing engineering, but unlike general machining or welding, it lacks a single canonical reference that every practitioner knows. The knowledge is scattered across academic monographs, industry standards from multiple continents, proprietary training programmes from tool manufacturers, and research journals that span mechanical engineering, geology, and petroleum engineering.
This article provides a structured guide to the key resources available to deep hole drilling professionals, organised by type — books, standards, training, and research outlets — with practical recommendations for engineers at different career stages.
Essential Books
The literature on deep hole drilling falls into three categories: general drilling monographs, specialised deep hole drilling references, and broader machining textbooks with substantial drilling content.
Dedicated Deep Hole Drilling Books
| Title | Author | Year | Coverage | Level |
|---|---|---|---|---|
| Drills: Science and Technology of Advanced Operations | Viktor P. Astakhov | 2014 | Drill design, cutting mechanics, tool wear, optimisation | Advanced |
| Deep Hole Drilling: A Practical Guide | D. Laughton | 2025 | Shop-floor practices, troubleshooting, process selection | Intermediate |
| Drilling Technology: Fundamentals and Recent Advances | J. Paulo Davim (ed.) | 2018 | Broad survey including deep hole, micro-drilling, composites | Intermediate–Advanced |
| 深孔加工与检测技术 (Deep Hole Machining and Inspection Technology) | Yu Daguo et al. | 2025 | Chinese-language comprehensive reference | All levels |
Astakhov (2014) is the most technically rigorous reference available on drill design and cutting mechanics. It covers the geometry of twist drills, gun drills, and BTA tools in detail, with analytical models for thrust force, torque, and tool wear. The book is essential for engineers who need to optimise tool geometry for specific materials or troubleshoot chronic tool failure modes. Its treatment of drill point geometry — including the mathematical description of flank surfaces — is unmatched in the English-language literature.
Laughton (2025) takes the opposite approach: practical, experience-based guidance for the shop floor. It covers process selection (when to use gun drilling vs. BTA vs. EDM), common defect diagnosis, coolant system troubleshooting, and inspection methods. Less mathematically demanding than Astakhov, it is the better starting point for newcomers to the field.
Davim (2018) is an edited volume with chapters from multiple authors covering drilling fundamentals, deep hole drilling, micro-drilling, drilling of composites and stacked materials, and computational modelling. The deep hole drilling chapter provides a solid overview of BTA and gun drilling processes with reference to recent research. The book is useful as a broad survey but lacks the depth of Astakhov on any single topic.
General Machining References with Strong Drilling Content
| Title | Author | Coverage |
|---|---|---|
| Fundamentals of Machining Processes | Hassan El-Hofy | Drilling section covers tool geometry, cutting forces, and surface integrity with worked examples |
| Modern Machining Technology | J. Paulo Davim | Includes BTA drilling, gun drilling, and trepanning in the context of advanced machining processes |
| Manufacturing Automation | Yusuf Altintas | Cutting force modelling directly applicable to drilling process optimisation |
| Metal Cutting Principles | Milton C. Shaw | Foundational text; drilling chapter covers chip formation, forces, and temperature |
Tip: For engineers new to deep hole drilling, start with Laughton (2025) for practical orientation, then move to Astakhov (2014) for the underlying theory. The two books together cover the theory-practice gap more completely than any single volume.
Chinese-Language Resources
The Chinese-language literature on deep hole drilling is extensive and in some areas ahead of the English-language corpus. Yu Daguo's 深孔加工与检测技术 (Deep Hole Machining and Inspection Technology, 2025) is the most recent comprehensive reference, covering BTA and gun drilling theory, process parameter selection, hole quality inspection, and common defect analysis. Engineers with Chinese reading ability should also consult back issues of Tool Engineering (工具技术) and Machining Science and Technology (机械科学与技术), which publish regular deep hole drilling research.
International Standards
Standards governing deep hole drilling equipment, tolerances, and test methods are spread across ISO, national standards bodies, and industry associations.
ISO Standards
| Standard | Title | Scope | Relevance to Deep Hole Drilling |
|---|---|---|---|
| ISO 18758-1:2018 | Mining and Earthmoving Machinery — Rock Drill Rig and Rock Reinforcement Drill Rig — Part 1: Safety Requirements | Safety requirements for rock drilling equipment | Safety framework for large-diameter deep drilling in mining and civil engineering |
| ISO 18758-2:2018 | Mining — Rock Drill Rigs — Part 2: Performance Parameters and Test Methods | Performance testing for rock drill rigs | Test methodology applicable to deep hole drilling performance evaluation |
| ISO 10098:2020 | Methods for Measuring the Performance of Rotary Core Drilling Equipment | Core drilling performance measurement | Measurement methods adaptable to deep hole drilling process qualification |
| ISO 22476-15:2016 | Geotechnical Investigation and Testing — Field Testing — Part 15: Measuring While Drilling | MWD data acquisition and interpretation | Data collection framework applicable to deep hole drilling process monitoring |
| ISO 286-1:2010 | ISO Code System for Tolerances on Linear Sizes | General tolerance system | Reference for specifying deep hole diameter tolerances (typically IT8–IT10) |
BTA Industry Standards
The BTA (Boring and Trepanning Association) has published two key standards that govern deep hole drilling tool dimensions and tolerances:
BTA-STS (Standard Tolerances — Boring):
- Covers diameters from 7.76 mm to 350 mm
- Defines tolerance classes for BTA deep hole drilling operations
- Typical achievable tolerance: IT9 for production drilling
- Reference for specifying bore diameter and straightness requirements in purchase orders
BTA-DTS (Standard Dimensions — Boring):
- Defines standard drill head diameters and shank dimensions
- Covers BTA single-tube and double-tube system tooling
- Ensures interchangeability between BTA tool manufacturers
- Critical for shops that use multiple BTA tooling suppliers
Warning: BTA-STS and BTA-DTS are proprietary industry standards published by the BTA association. They are not freely available and must be purchased from BTA member organisations. However, their tolerance specifications are widely referenced in the deep hole drilling industry and serve as the de facto benchmark for process capability.
Gun Drilling Standards
Gun drilling lacks a single comprehensive international standard comparable to BTA-STS/DTS. Instead, gun drilling process capability is defined by:
- Typical diameter tolerance: IT8 (approximately ±0.015 mm for 10 mm diameter)
- Typical surface finish: Ra 1.6–3.2 µm for standard operations, Ra 0.4–0.8 µm with optimised parameters
- Straightness: Industry practice of 0.5–1.0 mm per metre of depth, though this varies with material and machine condition
- National standards: Various national defence and aerospace standards specify gun drilling quality requirements for specific applications (e.g., MIL-SPEC for gun barrel drilling)
Reference Standards for Quality and Inspection
| Standard | Purpose | Application |
|---|---|---|
| ISO 4287 | Surface texture: profile method — terms, definitions, parameters | Specifying Ra, Rz for deep hole surfaces |
| ISO 2768 | General tolerances | Default tolerances when no specific tolerance is on the drawing |
| ISO 1938 | Geometrical product specifications (GPS) — dimensional tolerancing | Bore diameter and straightness specification |
| ASTM E1417 | Liquid penetrant testing | Surface defect inspection for deep holes |

FAQ
What is the best book on deep hole drilling for a beginner?
Laughton's Deep Hole Drilling: A Practical Guide (2025) is the best starting point. It covers shop-floor practices, process selection, and common troubleshooting without requiring advanced mathematics. For the theory behind the practice, move to Astakhov's Drills: Science and Technology of Advanced Operations (2014) once the practical fundamentals are solid.
What international standards govern BTA deep hole drilling?
BTA-STS (Standard Tolerances — Boring) defines achievable diameter tolerances from IT9 to IT12 depending on depth and material. BTA-DTS (Standard Dimensions — Boring) specifies standard drill head diameters and shank dimensions for interchangeability. These are proprietary industry standards published by the BTA association. ISO 18758 covers safety and performance for rock drill rigs in mining applications, while ISO 22476-15 defines measuring-while-drilling data collection for geotechnical work.
Is there free training available for deep hole drilling?
Yes. Sandvik Coromant Academy offers eight free self-paced online modules covering deep hole drilling tool selection, process parameters, coolant management, and troubleshooting. Sandvik, ISCAR, Kennametal, Mapal, and Botek all publish free technical guides and application handbooks. Tooling U-SME offers holemaking training on a subscription basis.
What is the difference between BTA-STS and BTA-DTS standards?
BTA-STS (Standard Tolerances — Boring) defines the achievable bore tolerances for BTA deep hole drilling operations, including diameter tolerances and straightness expectations. BTA-DTS (Standard Dimensions — Boring) defines standard drill head diameters and shank dimensions to ensure interchangeability between BTA tooling suppliers. Both are necessary for specifying deep hole drilling work to contract shops.
Which research journals publish deep hole drilling papers?
The primary journals are CIRP Annals (highest quality, BTA-focused), International Journal of Machine Tools and Manufacture (gun drilling and process modelling), Journal of Manufacturing Processes (optimisation and coolant research), Machining Science and Technology (tool wear and surface integrity), and Wear (tool wear mechanisms). For oil and gas deep drilling, SPE Drilling & Completion is the key publication.
