Ingco 8.0mm HSS-Co M35 Twist Drill Bit | Cobalt High-Speed Steel Jobber Drill for Stainless Steel and Hard Metals (DBT01130801)
Ingco 8.0mm HSS-Co M35 Twist Drill Bit | Cobalt High-Speed Steel Jobber Drill for Stainless Steel and Hard Metals (DBT01130801)
The Ingco DBT01130801 twist drill bit is an industrial-grade metalworking cutter engineered to penetrate high-tensile alloys and stubborn metals that standard high-speed steel bits fail to score. Featuring a precise 8.0mm diameter profile, this jobber-length bit is optimized for production-line drilling, structural steel fabrication, and demanding engineering or automotive repair applications where heat management is critical.
The bit is manufactured from premium M35 grade High-Speed Steel infused with 5% Cobalt alloy (HSS-Co). This cobalt enrichment significantly raises the tool's red-hardness—the ability of the cutting edges to maintain structural integrity and sharpness at elevated operating temperatures up to 600°C. To ensure fast penetration with minimal surface wandering, the bit features a 135-degree split-point tip layout, eliminating the need for a center punch on smooth surfaces. Precision-ground dual flutes facilitate rapid chip evacuation, minimizing thermal friction and preventing the bit from binding in deep-bore applications. Equipped with a standard straight shank, it integrates seamlessly into stable bench drill presses and heavy-duty hand drills.
