Currently, the straight flute drill hardware industry is very good enough, a lot of machinery and equipment can be applied to it, then straight flute drill which products characteristic?

Modern straight flute drill "pioneer" is a bit of mold (die drills), this short bit size, rigidity, strong drill tip for a lower spindle speed and feed rate smaller drilling hard steel material, its high strength and rigidity to enable it to process a superb straightness and roundness of the hole. Mold drill has been able to achieve good processing effect, because when the work material designed for drill usually produce short metal chips. Straight flute drill in processing applications, the chip control remains a key issue. To get the best results when only straight flute drill in processing materials that do not produce chips scroll whisker of these materials include cast iron, powder alloy (P / M), - the high silica content (6% or higher) aluminosilicate alloy.

Straight flute drill can significantly improve processing efficiency is partly based on the basic design of the drill - straight grooves are chips out of the hole provides a direct channel. However, the straight flute drill bit cutting edge is missing a positive rake angle, so its volume chips and chip breaking ability is poor, in the processing of malleable material particular.
