Straight Shank Exchangeable Solid Carbide Insert Spade Drill

1.This spade drill bit is designed for high precision drilling on thick metal sheets, stainless steel, and other materials. Approximately 1-5 times quicker than the ordinary drill bits, it is a true time-saver with its scientific cutting geometry, also could process multi-layer steel in one operation.

2.The high-precision connection between holder and cutting insert guarantees narrowest tolerances and cutting inserts that are easy to change.Different spade blades and insert holders(the drill bit body) are available to fit for your various processing conditions, suitable for CNC drilling, CNC 3D or compound drilling, CNC vertical milling, lathe machine, machine center, etc.

3.The optimized XR cross-sectional cutting edge grinding on the cutting inserts reduces the cutting forces significantly and improves the stability of the entire cutting insert.The chip breaker results in better chip removal and a lower cutting force.

4.Please note that violent impact between the blade and the contact surface may lead to blade breakage, please press down slowly before drilling. Avoid sudden drilling stop or reverse rotation when processing, the blade will be easily damaged under these conditions.

5.Internal coolant supply for excellent chip removal even when deep drilling.Proper coolant and reasonable coolant pressure setting are highly recommended for better drilling performance and long service life of the bit.
