With one drill for all materials, stock holding can be reduced and greater machine flexibility is offered leading to reduced set-up time, Sandvik Coromant claims.
The CoroDrill 460-XM is made from micro-grained carbide with a finishing treatment to reduce coefficient of friction. The web design provides improved cross-sectional strength that, along with increased flute volume, enhances chip evacuation. The point angle of 140° is suitable for multi-application drilling, with good centring 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.
