After tialn coated high-speed steel broaches, in geometry and tooth-liter capacity and other aspects were optimized, the use of semi-dry cutting, broaching under normal conditions, the life of the coating broach higher than uncoated broaches 20 % or more, and also good surface quality of the workpiece is pulled.

Use ø5mm9341 high-speed steel double rear angle 135 ° tialn whole ground drilling 185hb45 steel coated drills, in dry cutting, line speed 35m / min, 16mm deep blind hole drilling, the feed rate was increased from 0.10mm / r to 0.15mm / under r condition, the number of drilling by the 200 down to 80, compared with uncoated 1-fold increase bit life, efficiency increased by 2 times.

ø6mm m2 Würth drill steel rolling, the oxynitride process, drilling hrc31 ~ of 40crmnmos steel in dry cutting, line speed 25.2m / min, 18mm deep blind hole drilling, the feed rate at 0.10mm / r Conditions , 110 more than the number of drilling, is common with the specifications, 8 to 10 times the same material drill life. This high-performance drill high life, has been the "2006 China Famous Brand" products sold in Europe markets.
