Description
Overview:
The Timco 5-10 mm HSS De-Burring Countersink is a compact, high-speed steel tool for tidying drilled holes in metal and plastic. It removes burrs and forms neat chamfers so fasteners sit flush and edges are safe to handle. The transverse (cross) hole design provides a sharp cutting edge with good chip clearance for a smooth finish. Suitable for use in standard handheld drills and drill presses, it fits typical 3‐jaw chucks and is easy to control with light pressure. Covering a working range of 5-10 mm, it is ideal for common pilot and clearance hole sizes found in fabrication, installations, and general maintenance. Built from durable HSS, it offers reliable performance on everyday metals and engineering plastics.
Key Features:
- HSS construction for durability and consistent cutting on metal and plastic
- Working range 5-10 mm to cover common hole sizes
- Transverse (cross-hole) cutting geometry for clean, controlled de-burring
- Produces neat chamfers ready for countersunk screws and flush fittings
- Suitable for corded/cordless drills and pillar drills; fits standard 3-jaw chucks
- Compact cone profile reaches thin sheet, panels, and tight spots
- Reduces sharp edges and snag risks, improving safety and finish quality
- Effective on aluminium, mild steel, brass, and plastics such as acrylic and PVC
- Simple to use with light feed pressure; good control at moderate drill speeds
- Robust, low-maintenance design for site work, workshop use, and repairs
Typical Applications:
Ideal for deburring and chamfering holes in brackets, sheet metal, box section, conduit, machine guards, and plastic panels. Use after drilling to remove raised edges, prepare holes for countersunk screws, and improve fit and finish on assemblies. Useful in fabrication, HVAC, electrical installs, fencing, machinery maintenance, and workshop projects.
