SUMIDIA Coated Drills
MDS ... SDC SDC Type
General Features
SUMIDIA Coated SDC type drills for Carbon Fibre Reinforced Plastic
(CFRP) employ Sumitomo Electric Hardmetal‘s proprietary multi-step
point angle.
Combined with a diamond coating, this technology improves the
quality of machined surfaces and extends tool life.
Characteristics and Applications Series Diameter Point Hole Depth
Range (mm) angle (L/D)
l Excellent drilled-hole quality Type 2,0 ~ 4,0 ~3
- Sharp cutting edge shape reduces delamination of fibre 90°
layers and burrs. MDSSDC 3 4,851 ~ 10,0
- Continuously changing point angle disperses load placed 130°
on cutting edge and prevents breakage.
