Metal milling drilling drill by Yato YT-44821. Milling drill made of high quality high -speed HSS 4241 titan -covered titanium. Intended for professional, industrial applications. STAL HSS provides several times faster drilling in stainless, acid -resistant and structural steel. The "Split Point" cross blade with an apical angle of 118 ° allows drilling without prior scoring, also with large diameters of drilling, guaranteeing perfect centering. They enable drilling in every direction and at any angle, perfect for drilling holes, including for door locks. The ground surface ensures excellent drilling precision. Made of one piece of steel, making them very strong and durable. Hard coating 58–62 HRC coated with titanium nitride maintains resistance to damage and stretching, maintaining the geometry of drilling • Lower drilling temperature and rapid heat dissipation do not cause melting galvanized and subsequent corrosion of drills • The smaller friction factor limits the adhesion to the chips and filings. 1/4 ″ hexagon handle (6.3 mm).
