Bosch PRO 25 Piece HSS-Co Drill Bit Set

The Bosch PRO 25 Piece HSS-Co Drill Bit Set is a set of cobalt-alloy twist drill bits designed for drilling in stainless steel. Made from premium high-speed steel reinforced with cobalt (HSS-Co), these bits are ground for wear and heat resistance. They help you drill clean, precise holes without the bit wandering.

Each bit has a centring tip, so you can start a hole exactly where you need it. This supports accurate drilling and helps the bits keep performing for longer. The bits are made to DIN 338.

The set suits construction workers and installers who need long-lasting bits for stainless steel and other metals. It includes 25 sizes from 1mm to 13mm in 0.5mm steps, supplied in a ProBox case. The cylindrical shanks fit three-jaw drill chucks.

Features and Benefits:
• Long-life drilling in stainless steel
• Centring tip for accurate hole starts
• High-speed steel blended with 5% cobalt for strength and resistance to heat and wear
• Cylindrical shank compatible with three-jaw drill chucks
• 25 sizes from 1mm to 13mm in a ProBox case
