Product: Made in Japan
Manufacturer: DIJET
Model: EZN4D Type

Features

・New thinning geometry makes stable chip evacuation from biting till hole ends therefore,　possible to get accurate hole size and position.

・New margin shape has rigidity and burnishing action, which reduce frictional resistance and cutting force resistance. EZN5D type has double margin as well, it achieved excellent surface roughness, longer tool life with accrete hole.

・Due to the surface treatment can be helped to prevent build up edge and lower friction coefficient, therefore, can be avoided breakage problem caused by burr, stuck of chips.

・Adopted micro-grain carbide and DV coating which is good for oxidation and heat resistant.It achieved high accuracy and long tool life during high speed machining for various materials such as general steel, Mold steel, stainless steel.

Cutting performance

Because of low thrust, it achieved excellent biting property and stable drilling

By reducing cutting force and cutting heat,attaining excellent surface roughness

STRIKE DRILL achieved more than 2 times longer tool life compared with competitor K

Favorable chip shape from high speed machining to low speed machining

Specification

High accuracy solid drill
Drilling depth 4×Dc
Helix angle :30°
Without coolant hole

Tolerance for φDc

Recommended cutting conditions

Attention

*1. Above cutting conditions are for drilling flat surface.
Please adjust cutting conditions according to machine rigidity, work clamping and shape of machining part.
*2. Above cutting conditions are for drilling with water soluble (internal coolant)
*3. We expect 2D type’s depth of hole is less than 2D, 4D type is less than 4D.
*4. In case of long chips evacuated, adjust above conditions by increasing Feed speed or using step feed for breaking chips
