Lead precision is the best in the world.
Finish size is ƒΣ3 to ƒΣ20. Stock products in 1-mm increments can be delivered immediately.Standard length is 320, 250, and 200mm.The precision of lead length essential to drill material that is the main use is the best in the world (according to our research). It prevented hole breakdown in groove grinding.Twisted 2-coolant hole carbide rod below ƒΣ3 mm can be manufactured. Contact us.
