Tackle the toughest metals with confidence using this ROKTOR 7-piece cobalt drill bit set. Made from M35 high-speed steel with 5% cobalt, these bits are specifically designed to withstand the high heat of drilling into stainless steel and other hard alloys.

The bits feature a 135° split tip, which prevents the bit from "walking" across your material and ensures an immediate, precise start. This set provides a versatile range of sizes from 1.5mm to 6mm for professional site use.

• M35 5% cobalt steel – provides superior heat resistance for hard metals
• 135° split tip – ensures an accurate start with no pilot hole needed
• Fully ground – delivers sharp edges and high precision
• 7-piece set – includes common sizes from 1.5mm up to 6mm
• Durable storage – keeps bits organised and protected on the job
