SUMIDIA COAT Drill SDC Type ■ General Features SUMIDIA Coated SDC type drills for Carbon Fiber Reinforced Plastic (CFRP) employ the proprietary multi-step point angle. Combined with a diamond coating, this technology improves the quality of machined surfaces and extends tool life. ■ Series Diameter Point Drilling Depth Cat. No. Range (mm) angle (L/D) ø2.0 to ø4.0 90° MDS□ □ □ □ □SDC3 Type Up to 3 ø4.851 to ø10.0 130° ■ Characteristics · Applications D Excellent drilled-hole quality External Coolant Supply · Sharp cutting edge shape reduces delamination of fibre layers and burrs. Carbon Steel, Alloy Steel Tempered Hardened Steel Stainless Ti Heat-resistant Cast Ductile Aluminum Copper Composite Up to 0.28% From 0.29% Steel Up to 45HRC From 46HRC Steel Alloy Steels Iron Cast Iron Alloy Alloy CFRP · Continuously changing point angle disperses load D S G placed on cutting edge and prevents breakage. D Long tool life · Use of high-strength diamond coating with excellent 3D adhesion delivers high quality and long tool life. ● Diameter ø2.0 to ø4.0mm ■ Performance LU PL DMM h6 DC h8 Comparison of Machined Surface Finish 90° LCF Excellent Machined Face Finish OAL [Prevents Delamination And Burrs] SDC Type Comp.
