The CoroDrill 460-XM is made from micro-grained carbide for an excellent combination of hardness and toughness, resulting in high wear resistance and longer tool life. The coating has a special finishing treatment to reduce coefficient of friction.
The strong web design provides excellent cross-sectional strength that, combined with increased flute volume, enhances chip evacuation. The point angle of 140 deg is ideally suited for multi-application drilling, with good centering capabilities and low thrust force design. The drill comes in a standard diameter range of 3–20 mm (0.118–0.787 inch) in drill lengths; 2–5 × drill diameter (DIN 6537 K and DIN 6537 L). Achievable hole tolerance: IT8–IT9 and is available with internal and external coolant.
