Makita D-17398 HSS Cobalt 6.5mm Drill Bit

Summary

The Makita D-17398 is a 6.5mm HSS-Co (M35) cobalt twist drill bit designed for precision drilling in demanding metalworking applications. Built to DIN338 standard with 5% cobalt content, it delivers superior heat and wear resistance compared to standard HSS bits. Suitable for tradespeople and engineers working with hard or difficult-to-machine metals.

Features

• Manufactured to DIN338 standard using M35 high-speed steel with 5% cobalt content for enhanced strength and longevity.
• Cobalt alloy construction provides maximum heat and abrasion resistance when drilling hard materials.
• 135deg split-point tip geometry prevents bit walking, enabling fast and accurate starts without centre-punching.
• Precision-ground forged edge and flute construction ensures high-quality performance and extended service life.
• Suitable for drilling mild steel, stainless steel, cast iron, high-alloy materials, welded seams, and car bodywork.
• Anti-slip angled tip reduces the risk of bit slippage during initial penetration.
• Stronger and longer-lasting than conventional HSS drill bits, reducing downtime and replacement frequency.
