50mm High Speed Steel Twist Drill Bit | 118° Spiral Design for Iron/Steel/Aluminum/Copper | 3 / 4in Small Shank for Electric Drills & CNC Machines

Produktbeschreibung

Spiral Chip Removal - Twist drill bit features efficient spiral design that saves effort during drilling tasks. Optimized for quick debris removal in metalworking applications. HSS Construction - High speed steel material delivers exceptional hardness (HRC62-65) and performance. Maintains sharpness through 300+ drilling sequences without deformation. Exact 118° Point Angle - Glossy flute geometry enables swift cutting at 800-1200 RPM. Achieves 40% quicker penetration versus conventional 135° bits in stainless steel applications. Universal 3/4in Shank - Standard shank diameter (19mm) ensures secure fit in all electric drills and CNC machines. Secure-grip design prevents bit wobble during high-torque tasks. Multi-Metal Compatibility - Industrial-grade bit drills through hardened steels (HRC45), manganese alloys, and non-ferrous metals. Includes extended breakage coverage against manufacturing defects.
