This bit size short, rigid, strong drill tip for a lower spindle
Speed ​​and smaller feed rate drilling hard steel material, its high strength and rigidity to enable it to process a superb straightness and roundness of the hole. Mould
Drill has been able to achieve good processing results, because the design of the drill when the work material is usually produced short against metal chips. In the straight groove
Bit processing applications, chip control remains a key issue. Straight flute drill in the processing of those materials will not only produce chips scroll whisker
When to get the best results, these materials include cast iron, powder alloy (

However, with the machine tool technology, coolant supply and tool geometry design technology advances straight slot drill range of processing applications are not

Straight flute drill can significantly improve processing efficiency is partly based on the basic design of the drill bit

Straight grooves are chips out of the hole provides a straight
Access channel. However, since 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 relatively ductile
Especially when good material.

Modern straight flute drill "pioneer" drill 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 results, because the design of the drill when the work material is usually produced short against metal chips. Straight flute drill in processing applications, 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 whiskers. These materials include cast iron, powder alloy (P / M), - the high silica content (6% or higher) aluminosilicate alloy. However, with the machine tool technology, coolant supply and tool geometry design technology advances straight slot drill range of processing applications is expanding. The traditional way of thinking that the drill spiral groove for chip removal is essential, straight flute drill can only be used on aluminum and cast iron drilling holes deep 2D ~ 3D (D is pore diameter) shallow holes. But now the development of the high-pressure cooling system and higher spindle speed, so that the use of the cooling straight slot drill chip breaking and chip performance greatly improved.
