Features
By adopting TRI-Cooling technology optimized for small diameter drills, the coolant discharge volume has been more than doubled compared to conventional models.
Chip evacuation performance and cutting heat dissipation performance are greatly improved, greatly contributing to life stability.

Use
For small diameter hole machining.
Work material: steel, stainless steel, cast iron.

Specification
Blade diameter (mm): 1.0
Groove length (mm): 28.2
Total length (mm): 73
Shank diameter (mm): 4
Effective machining depth: 25
Point angle (): 139
Surface treatment: Super multi-layer PVD coating – Neck length (mm): 33.8

Specification2
Surface treatment: Ultra-multilayer PVD coating
By adopting TRI-Cooling technology optimized for small-diameter drills, the coolant discharge amount is more than twice that of the conventional ratio
The increased coolant discharge amount allows the cutting edge to be efficiently possible to cool

Material/Finish
Ultra-fine particle cemented carbide (UWC)
