Material Description SKD11's steel grades are GB Cr12MoV in China, JIS SKD11 in Japan,
AISI / SAE D2 in USA, DIN 2X165CrMoV12 in Germany.
SKD11 belongs to mold tool steel, and it is also a kind of high-carbon alloy steel. It has both high hardness,
; high strength, and abrasion resistance,
; and its surface is precisely ground, which is suitable for making blades.
Chemical composition (JIS G4051) (C)% : 1.4~1.6
; (Si)% : 0≦0.4
(Mn)% : 0≦0.6
(P)% : 0≦0.03
(S)% : 0≦0.03
(Ni)% : 0≦0.5

Crush Cut Knives
Precision blade
Each blade will undergo special precision grinding and control of each blade's roundness to reach +/-0.005mm before the product leaves our factory. The precision blade with fine grinding hardness backing roller and through A310/A310H half-cut knife holder depth adjusting allows you to cut as depth as you want.
Guide-bar
GB05
GB05 is the new generation of the Guide-Bar series. It has the advantage of the linear guideway groove, side-fixed installation, lightweight, and fast delivery. Besides, there are two lengths of guide-bar to choose from, 2000mm and 2400mm.
Crush Cut Knives
130T Unibody Zigzag knife
The 130 teeth zigzag blade is made of tool steel (SKD-11) imported from Europe, processed by well heat treatment to increase its mechanical properties such as toughness and wear resistance. The blade tip is precisely ground to maintain an equal tooth pitch and peak, the slitting edge will generate the zigzag notch, to facilitate tearing along the notch. The zigzag blade is suitable for easy-tear applications such as medical tapes.
Bearing
5.0mm/6.2mm Bearing
Bearings for score blade, there are two different model , 697ZZ is for 5.0mm thickness and 17mm inner diameter score blade ; 6900RS is for 6.2mm thickness and 22mm inner diameter.
