Drill File Bit with 8 mm Shank for Wood STANLEY STA66155 — Cylindrical 16×30 mm

STANLEY Drill File Bit with 8 mm Shank (cylindrical 16×30 mm) is a rasp-style rotary attachment for power drills intended for woodworking tasks. The bit features an 8 mm straight shank for compatibility with chucks that accept this diameter and a cylindrical working head measuring 16 mm in diameter and 30 mm in length. It is designed for shaping, leveling, smoothing and rapid material removal on wooden surfaces, edges and profiles.

Advantages

The cylindrical rasp profile provides consistent stock removal and an even surface finish when compared to flat files. The 8 mm shank ensures secure seating in standard drill chucks, reducing wobble during operation. The compact 16×30 mm working head gives good access to confined areas and makes it suitable for detail work. Made to the brand’s quality standards, the bit is intended to offer reliable performance for common woodworking tasks.

Suitable for

• Shaping and trimming wooden edges and mouldings
• Smoothing rough-sawn surfaces and removing excess material
• Detail work on carvings, furniture components and joinery
• Preparing wood surfaces for sanding or finishing

Key specifications

• Type: cylindrical rasp rotary file
• Shank diameter: 8 mm (straight shank for drill chucks)
• Working head diameter: 16 mm
• Working head length: 30 mm
• Material suitability: wood and wood-based materials

How to use

Install the bit firmly into the drill chuck and tighten according to the drill manufacturer’s instructions. Operate the drill at moderate speed and apply steady, controlled pressure while moving the bit along the area to be shaped or smoothed. For best results, work progressively and remove small amounts of material rather than forcing large cuts. Keep the tool perpendicular to the surface when uniform removal is required, and change approach angle for shaping profiles or contours.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and a dust mask when working with wood. Test the bit on scrap material to determine optimal speed and pressure before working on the final piece. Avoid forcing the bit at excessive speeds to reduce wear and heat buildup; periodically clear accumulated wood shavings from the rasp surface to maintain cutting efficiency.
