high cutting requirements and long life twist drill bits sets for wholesale

Product Overview

Description

PRODUCT NAME	Drill
PRODUCT MODEL	Riken HSS drill
BRAND     NAME	Riken

Development objectives are a cutting speed of 50 m/min.

1. Adopt unequal leads
By adopting appropriate twist angles at the tip and rear end of the groove, the high rigidity and the dischargeability of the chips can be achieved at the same time, and the service life can be extended.
Even a deep hole of 8*D can be machined in a non-step manner.

2. Adoption of W margin
The W margin can be processed without increasing the cost.
In addition, since the walking phenomenon of the chisel can be suppressed,
  Improved hole accuracy.
Stabilization of life.
  Reduction of troubles during punching.
  To reduce wear on the peripheral margin
This results in a significant improvement in accuracy and processing efficiency.

3. Highly abrasion-resistant TiALN coatings
We have achieved high cutting requirements and long life by applying the best TiALN coatings that can be considered at present.
It is ideal for machining that is less susceptible to cutting oil.

4. Developed and adopted the highest-quality high-speed RHX1
We have developed and adopted a RHX1 capable of HRc70 hardness without impairing toughness.
In addition, the hardness of the powder heights is realized with the required heights.
It offers powder-high performance at low cost.
