High precision geometry withgood fracture resistance

2 flute CBN long neck ball nose slot drill

2 flute CBN long neck radius end mill

The realization of excellent performance whenmilling hardened steel over 65HRC.

CBN end mill series, the ultimatechoice for finish machining of molds.

Feature 1

An original manufacturing method allows a wide variety of neck lengthsFeature 2

Cutting edge geometry that offers excellent chip disposal enables long, stable operations.Excellent performance over a wide array of machining applications due to the precision of the seamless cutting edge geometry. Radius tolerance ±5μm, diameter tolerance 0~-10μm.

Conventionaltechnology

The neck is inserted into the shank and brazed.

It’s impossible to increase the neck length.

Possible to increase the neck length.

(Inserted brazed method)

[Diffusion Bonding] (PAT.P)

Low bonding strength

Newly developed method of joining.Bonding strength is the same as the carbide material.

* Example: R1 neck length of 5mm extended to 20mm.(.039" R neck length .196" extend to .787")

CBN material with good fracture resistance enables the machining of 70HRC hardened steel.2 variations, long neck ball nose and long neck radius types available.Long neck ball nose type

Capable of a large pick feed for high efficiency finishing of flat faces.High precision design with radius tolerance of ±5µm
