RUKO SPB-DIN338-HSSCo8-Ø16.0mm HSS-Co8 Twist Drill Bit

Drilling into high-alloy steels, stainless steel, cast iron, bronze, or hard plastics demands a bit that resists heat and wear without losing its edge. The RUKO SPB-DIN338-HSSCo8-Ø16.0mm twist drill bit meets that challenge with a cobalt-alloyed HSS-Co8 body and a 130° split point that starts on contact and cuts cleanly.

Who is it for

This bit is built for industrial metalworking and maintenance professionals who need reliable performance in tough materials. It suits workshops, fabricators, and machine operators drilling precise 16 mm holes in demanding alloys and hard plastics.

Main features

• HSS-Co8 high-speed steel with 8% cobalt for high heat and wear resistance.
• DIN 338 standard dimensions: 178 mm total length, 120 mm working length.
• 130° split point for accurate starting and reduced walking.
• Fully ground, bright finish for precise cutting geometry.
• Right-hand cutting, cylindrical shank with h8 tolerance.

Tips

Use a cutting fluid or coolant when drilling stainless steel or high-alloy steels to extend tool life. Ensure the workpiece is securely clamped and the drill is held rigidly to avoid deflection at this diameter.
