Twist drill bit KWB 258025 Right hand rotation 1 pc

Twist drill bit KWB 258025 is a right-hand rotation HSS M2 spiral drill designed for drilling a wide range of materials. The bit features a 130° point angle with a special polished section and a Quick Cut spiral geometry that produces short swarf and supports optimal chip evacuation. It has a reinforced core, an extra-robust design and is especially heat-resistant, delivering reliable cutting performance in stainless steels as well as in other steels, cast iron and cast steel. The drill is intended for use with cordless and corded machines and is supplied as a single cylindrical-shank piece.

Advantages

The HSS M2 material and reinforced core provide durability and resistance to wear and heat. The 130° point with polished cutting section and the Quick Cut spiral geometry reduce cutting forces and generate short chips for easier evacuation. Extra-robust construction and specially shaped short spiral notch improve stability and prevent breakage during demanding drilling. The cylindrical shank ensures secure mounting in standard chucks.

Suitable for

• Drilling stainless steel
• Drilling various carbon steels
• Drilling cast iron and cast steel
• General metalworking tasks with cordless or corded drills

How to use

Secure the KWB 258025 twist drill bit in the drill chuck so the cylindrical shank is fully seated. Select a suitable spindle speed and feed rate for the material being drilled — lower speeds for stainless steel and harder alloys, higher speeds for softer steels. Use steady, moderate pressure and allow the drill to cut without forcing. Clear chips regularly and, when drilling stainless steel or other heat-sensitive materials, consider intermittent drilling or backing off to improve cooling.

Usage recommendations

For best results when drilling stainless steel, use cutting lubricant or coolant and reduce speed to limit heat buildup. Replace the bit if cutting performance decreases or if visible wear or chipping appears on the polished cutting edges.
