What Are Boring Tools?

Boring tools are hand or machine-operated instruments specifically designed to create, enlarge, or refine holes in various materials — most commonly wood and metal. Unlike a standard drill that simply bores straight through a material, boring tools are engineered for precision: they control diameter, depth, surface finish, and positional accuracy to levels that general-purpose drilling cannot achieve.

The term 'boring' in this context has nothing to do with being dull — it comes from the Old English word borian, meaning 'to pierce.' From a humble bradawl to a CNC fine boring head, these tools have shaped woodworking and manufacturing for centuries.

Types of Boring Tools for Woodworking

Woodworking demands clean, accurate holes without splitting or tearing the grain. Here are the most essential hand and power boring tools every woodworker should know:

 

1. Brace

The brace is one of the oldest and most recognizable boring tools in woodworking. It consists of four main parts — head, crank, chuck, and ratchet — and operates by turning the U-shaped crank to drive a bit into the wood. The ratchet brace allows the user to bore in tight corners where a full rotation isn't possible, making it incredibly practical for confined spaces.

• Plain brace: basic, full-rotation operation

• Ratchet brace: bi-directional ratchet mechanism for tight spaces

 

2. Wheel Brace (Hand Drill)

The wheel brace functions similarly to the ratchet brace but uses a gear-driven wheel mechanism for smoother, faster operation. It accommodates standard drill bits, twist drills, and brad point bits, making it a versatile companion for light boring tasks without the need for power tools.

 

3. Bradawl — The Classic Boring Tool

The bradawl is arguably the most famous boring tool in the English language — not least because it's the go-to answer for the crossword clue 'boring tool.' But its fame is well-earned in the workshop too.

A bradawl is a small, pointed hand tool used to create starter holes in wood before inserting screws or nails. It works by pressing and twisting the sharp steel tip into the surface, parting the wood fibers rather than removing material. This minimizes splitting, especially in hardwoods.

• Handle: typically wood or plastic, designed for firm grip

• Tip: flat chisel-edged or round-pointed steel point

• Best for: softwoods, pilot holes for screws, joinery work

• Fun fact: the bradawl is also the most common answer for the crossword clue 'boring tool (7 letters)'

 

4. Gimlet

Similar in purpose to the bradawl, a gimlet is a small T-shaped or pistol-grip boring tool with a threaded or tapered point. Unlike the bradawl, the gimlet actually removes material as it turns, cutting a clean circular hole rather than splitting the fibers apart. Gimlets are ideal for starting holes in dense hardwood and for pilot holes in tight spots where a brace won't fit.

 

5. Auger

The auger is a spiral-fluted boring tool designed for deep hole boring in wood. Its helical design continuously pulls material upward and out of the hole, preventing clogging even when boring to significant depths. Augers come in a wide range of diameters and lengths:

• Spoon bit auger: traditional curved tip, used with a brace

• Twist auger: spiral flutes with a threaded lead screw for self-feeding

• Ship auger: heavy-duty, long reach for timber and construction work

 

6. Forstner Bit

Named after its inventor Benjamin Forstner, the Forstner bit creates exceptionally flat-bottomed, clean-edged holes — ideal for cabinet hinges, furniture hardware, and overlay joints. Unlike most boring tools, a Forstner bit is rim-guided rather than center-guided, meaning it can bore overlapping holes, angled holes, and holes right at the edge of a board without wandering.

 

7. Spade Bit (Paddle Bit)

The spade bit features a flat, paddle-shaped cutting tip and is designed for fast, rough boring through softwoods and sheet timber. While it won't win awards for hole quality, it's affordable, widely available, and perfectly suited for utility work where appearance isn't critical — running cables through walls, for example.

 

8. Brad Point Bit

The brad point bit has a sharp center point flanked by two raised spurs that score the wood before the main cutting edges remove material. This design prevents the bit from wandering on the surface and produces extremely clean, tear-free entry and exit holes. Brad point bits are the preferred choice for dowel holes, shelf pin holes, and any application where accuracy and surface quality matter.

 

Types of Boring Tools for Metalworking

In metalworking and precision machining, boring tools take on an entirely different form — and level of precision. Where woodworking boring tools operate by hand or with a simple drill press, metalworking boring tools are typically mounted in lathes, milling machines, or dedicated CNC boring machines, and they work to tolerances measured in thousandths of an inch.

 

1. Boring Bars

The boring bar is the foundational metalworking boring tool. It's a rigid, cylindrical bar that holds a single-point cutting insert at one end and is clamped into the machine spindle at the other. As the workpiece or the bar rotates, the cutting edge removes material from the interior of an existing hole to achieve the desired diameter and surface finish.

• Solid boring bars: maximum rigidity for standard-depth operations

• Vibration-damping boring bars: contain internal mass-damper mechanisms to absorb chatter during deep boring — critical when the bar's length-to-diameter ratio exceeds 4:1

• Carbide-tipped bars: excellent for high-temperature, high-speed applications and abrasive materials

 

2. Rough Boring Heads

Rough boring heads are used for the initial enlargement of a drilled or cast hole. They accept indexable square inserts capable of withstanding high feed rates and aggressive cuts. The goal at this stage isn't a perfect finish — it's material removal efficiency, preparing the hole for a finishing pass.

 

3. Fine Boring Heads

After rough boring, fine boring heads deliver the final precision pass. These adjustable tools allow the operator to dial in the exact diameter — often to within 0.001mm — using a micrometer-style adjustment ring. Fine boring heads are indispensable in aerospace, automotive engine work, and any application with tight dimensional tolerances.

 

4. Back Boring Tools

Back boring tools are designed for a specific challenge: cutting the inside of a bore in a direction opposite to the normal feed direction, or machining features in areas inaccessible from the front face. They're commonly used to create undercuts, reliefs, and internal recesses that would be impossible to reach with a standard boring bar.

 

5. Reamers

While technically in a separate category, reamers are closely related to boring tools and often used in the same sequence. A reamer follows a boring operation to bring a hole to its final finished size with exceptional dimensional accuracy and surface finish. Reamers are available in hand, machine, and adjustable versions, covering a wide range of diameters and materials.

Frequently Asked Questions

What is a boring tool used for?

A boring tool is used to create, enlarge, or finish holes in wood, metal, or other materials. In woodworking, boring tools range from hand-operated bradawls and gimlets to power-driven Forstner bits and augers. In metalworking, precision boring bars and boring heads produce exactly-sized holes in engine blocks, aerospace components, and industrial machinery.

 

What is a bradawl?

A bradawl is a small, pointed hand tool used to create starter holes in wood before driving in screws or nails. It has a sharp, chisel-edged or round steel tip and a wooden or plastic handle. The bradawl works by pressing and rotating into the wood surface, parting the fibers to create a guide hole. It is also the most common answer to the crossword clue 'boring tool (7 letters).'

 

What is the difference between a gimlet and a bradawl?

Both tools create small pilot holes in wood, but they work differently. A bradawl splits wood fibers by pressing in with a chisel-edged point, while a gimlet removes material by cutting a clean circular hole with its threaded or tapered point. For hardwoods, a gimlet generally produces a cleaner hole; for quick work on softer timber, a bradawl is faster.
