Core drills can drill up to 10 times quicker then standard spiral drill bits. 。 Core drills only cut where the teeth are so the core is left intact. 。 Lower energy consumption and slippage increases the life of the tool. 。 With further developments in the cutting geometry a markedly better cut can be reached that has a positive effect on the cutting performance and service life. 。 Centring, pre-drilling and drilling out are no longer necessary. 。 Size Name:4.0mm 。 Core drill made of high-speed steel. Suitable for steel (such as I-beam, large-sized sheets), cast steel, non-ferrous and light metals. With an advanced blade geometry, a significantly improved cutting performance is achieved, which has a positive effect on the cutting performance and tool life. Optimised cutting edge geometry for increased cutting performance and reduced cutting forces. The rake angle is designed for universal use in various types of steel. Improved chip evacuation by U-shaped notching. The special geometry of the notching reduces the thermal load on the high-speed steel, the core drill, since the heat generated during machining is largely removed with the chip. 4 Reduction of the friction occurs between the high-speed steel core drill and the workpiece through optimised, spiralling circular guiding chamfers. Specifications: Diameter: 4.0 mm Overall length: 6.0 mm Cutting: High-speed steel Depth of cut: 0 mm Mounting: Weldon shank, 9.0 mm (/4 inch) Machine: TX 900 Surface: bright Right-hand cutting 。 。 。
