Hole saw drill bit BAHCO 3834-DRL-CT, diameter 6.35 mm, for metal and wood

BAHCO 3834-DRL-CT is a 6.35 mm diameter pilot drill designed for use with carbide holesaws to create accurate round starter holes in metal and wood. The compact accessory fits most standard arbors (excluding arbors with a core ejector function) and features a carbide-tipped pilot drill that produces a guiding hole before the holesaw teeth engage, ensuring correct alignment during sawing operations. Its construction and tip geometry are engineered to perform across a wide range of machinable materials in workshop and construction settings.

Advantages

The carbide tip delivers high hardness and wear resistance, extending service life compared with standard HSS pilots. By creating a precise pilot hole first, the drill reduces wobble and improves the accuracy of small-diameter through-holes in both metal and wood. Compatibility with most common arbors makes it a versatile accessory for technicians and tradespeople who use carbide holesaws. The product is supplied in retail packaging for convenient storage and handling.

Suitable for

• Making starter/guide holes for small-diameter holes in metal sheets
• Creating pilot holes in wood before holesaw cutting
• Workshop and site drilling where accurate alignment for holesaws is required
• General preparatory drilling for installation of bushings, fasteners, and wiring passages

Key specifications

• Pilot drill diameter: 6.35 mm
• Tip material: high-grade carbide
• Compatibility: fits most standard holesaw arbors; not compatible with core-ejector arbors
• Intended work materials: metal, wood, and other machinable materials
• Pack format: retail packaged

How to use

Install the pilot drill into a compatible holesaw arbor according to the arbor manufacturer’s instructions, ensuring secure clamping. Use the assembled holesaw and pilot in a drill or driver with appropriate speed and torque for the work material. Position the pilot point on the marked drilling location and apply steady axial pressure to let the carbide tip cut the guide hole; once the pilot is established, continue cutting with the holesaw while maintaining firm control to avoid lateral movement.

Usage recommendations

Use appropriate cutting speeds and apply cutting fluid or coolant when drilling metals to reduce heat and extend tool life. Wear suitable personal protection equipment including eye protection and gloves. Do not use this pilot with arbors that have a core ejector function. Inspect the carbide tip before use and replace when worn or damaged to maintain hole accuracy.
