This step cone drill bit is a high speed steel hole cutter designed for precise, clean drilling across multiple materials. It features automatic deburring to eliminate rough edges as you drill, and nitrogen treatment that increases hardness and abrasion resistance for extended tool life.
The 14-size set covers a range of 4mm to 42mm diameters (4, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42mm), making it suitable for most workshop and trade applications. It performs well on thin iron plate, aluminium, insulation boards, timber, and PVC sheets up to 4mm thick.
The round shank design fits standard drill chucks for straightforward setup. High speed steel construction ensures durability across repeated use, while the stepped profile delivers both efficiency and a clean finish.
This is a complete set in one package—no additional bits needed to cover your common drilling sizes. Check your current hole sizes and compare them against the 14 included steps to confirm coverage for your project.
