Description

This 4-piece countersink and chamfer drill bit set is designed for clean deburring, beveling, and countersinking of circular holes on various soft metal and plastic surfaces. Each bit is made from HSS4241 high-speed steel with a titanium coating for enhanced durability, sharpness, and heat resistance.

Perfect for tradespeople, metalworkers, and DIY users, this set supports a wide range of applications including deburring aluminium, mild steel, PVC panels, wood, and plastic boards. The internal crosshole design improves chip removal and reduces clogging during cutting, delivering smoother, more efficient hole finishes.

Features

  • High-Speed Steel Construction: Made from HSS4241, known for its balance of toughness and cutting precision in non-hardened materials.

  • Titanium Coated Surface: Reduces friction and extends tool life, especially under repeated or high-speed use.

  • Fast and Clean Chamfering: 90-degree cutting angle for smooth edges and clean chamfer finishes on drilled holes.

  • Crosshole Deburring Design: Allows chips to exit more effectively from the side, preventing clogging and overheating.

  • Wide Material Compatibility: Ideal for use on aluminium, mild steel, PVC, plastics, and similar low-hardness materials (below HB 28).
