V-Point Drill Bits for Through-Hole Drilling

Precision V-Point Drill Bits for Clean Through Holes

V-point drill bits, also known as through-hole boring bits, are designed for drilling completely through wood and engineered panels while minimizing chipping and breakout as the drill exits the material.

Their specialized cutting geometry helps produce clean exit edges, making these drills particularly useful in cabinet manufacturing, furniture production, closet systems, and other applications where both faces of the panel may be visible.

GDP Tooling supplies carbide-tipped and solid carbide V-point drill bits for CNC drilling machines, multi-spindle boring units, and industrial woodworking applications.

Series 6028 Carbide-Tipped V-Point Drill Bits

GDP Tooling’s Series 6028 carbide-tipped V-point drill bits are designed for accurate through-hole drilling in solid wood, MDF, particleboard, plywood, and laminated panels.

These drills feature carbide cutting edges for wear resistance and reliable performance in repetitive production environments.

Each bit incorporates a 10 mm shank with a clamping flat for set-screw retention and a height-adjustment screw for accurate positioning in compatible drilling units.

Available in multiple cutting diameters and right-hand or left-hand rotation configurations, Series 6028 drills provide a practical solution for high-production CNC woodworking.

57 mm, 70 mm & 77 mm V-Point Drill Bits

GDP Tooling offers carbide-tipped V-point drill bits in three overall lengths to accommodate different drilling unit configurations.

57 mm Overall Length

A compact configuration for compatible industrial drilling units and standard through-hole applications.

70 mm Overall Length

Provides additional overall length for drilling units or setups requiring a different tool projection.

77 mm Overall Length

An extended-length configuration for compatible drilling equipment where additional reach or a specific tool length is required.

When selecting a drill length, consider the machine’s mounting requirements, flute length, available drilling depth, and workpiece thickness.

Overall tool length should not be confused with maximum usable drilling depth.

Series 6028SC Solid Carbide V-Point Drill Bits

For applications requiring increased wear resistance, GDP Tooling offers Series 6028SC solid carbide V-point drill bits.

Solid carbide construction provides excellent cutting-edge durability and can be advantageous in demanding CNC drilling operations, particularly when machining abrasive engineered wood materials.

Series 6028SC drills are available in selected diameters and lengths, including 57 mm and 70 mm configurations.

These tools are suitable for precision through-hole drilling where consistent hole quality and reliable cutting performance are important.

Why V-Point Geometry Matters for Through-Hole Drilling

When a conventional drill exits the underside of a wood-based panel, the remaining material can fracture before the cutting edges complete the hole.

This can cause chipping, breakout, or damage to decorative surface layers.

V-point drilling geometry is designed to reduce this problem by providing a more controlled cutting action as the drill penetrates the opposite face.

This is especially important when machining melamine-faced particleboard, laminated MDF, plywood, and other materials where visible surface damage is unacceptable.

Hole quality also depends on drill sharpness, correct feed and speed, workpiece support, and machine setup.

V-Point vs. Brad Point Drill Bits

Although both drill types are commonly used in industrial woodworking, they are designed for different applications.

V-Point Drill Bits — Through Holes

Designed for holes that pass completely through the workpiece, with cutting geometry intended to minimize exit-side chipping.

Brad Point Drill Bits — Blind Holes

Designed for accurately positioned holes that stop within the material, such as dowel holes and certain furniture hardware applications.

Selecting the correct drill geometry helps improve hole quality and reduce unnecessary tool wear.

Right-Hand & Left-Hand Rotation

Industrial woodworking drilling units may require right-hand or left-hand rotation tools.

GDP Tooling offers V-point drill bits in both configurations, depending on the selected diameter and length.

Before ordering replacement drills, verify the machine’s required rotation direction, cutting diameter, overall length, and shank configuration.

Proper Mounting of CNC Through-Hole Drill Bits

Series 6028 and 6028SC drill bits feature a 10 mm shank with a clamping flat and height-adjustment screw for mounting in compatible industrial drilling units.

When these drills are used in a conventional precision collet chuck, clamping directly over the shank flat can interfere with proper concentric gripping.

A suitable cylindrical-shank adapter provides an alternative mounting arrangement for compatible CNC tool holders.

Correct mounting, minimal runout, and appropriate drilling parameters are essential for achieving clean through holes and avoiding premature tool failure.

Selecting the Correct V-Point Drill Bit

When selecting a replacement through-hole drill bit, consider:

• Required cutting diameter and hole tolerance
• Carbide-tipped or solid carbide construction
• Overall length and usable drilling depth
• Right-hand or left-hand rotation
• Workpiece material and surface finish requirements
• Drill shank dimensions and mounting method
• CNC machine or drilling unit compatibility

GDP Tooling provides technical assistance in selecting precision V-point drill bits and compatible mounting solutions for industrial woodworking and CNC through-hole drilling applications.
