Replaceable Tip Drills SMDT-NAL - DLC Coated for Non-ferrous & Aluminum Alloys
■ SMDT-NAL - DLC Coating Features & Benefits
l Low friction coefficient allows for higher penetration rates Feed Rate Drill Diameter = Penetration Rate l Ultra smooth coating surface allows for stable chip evacuation. l Aluminum welding resistance achieves excellent surface finish, and precision accuracy. l High hardness coating(60 GPa) has superior abrasion resistance.
■ Application Examples
Interrupted Hole
Solid Hole
Pre-cast Hole
Spot facing with WDX will increase position accuracy
250 - 300% less cutting force than uncoated carbide
Stable drilling, and stable chip evacuation

■ SMDT-NAL Increased Penetration Rate
SMDT-NAL - DLC Aurora Coating Max Penetration Rate: 7.5% New SMDT-NAL-DL1500 Aurora coa�ng reduces cu�ng forces by 250-330%. Achieving feed-rates 2-3x higher than conven�onal coa�ng!
l DLC Aurora coating reduces friction by 250%-330% l Allows for higher feed-rates and increased productivity l Helps to reduce cost per unit and decrease drilling cycle time Conventional Coating Max Penetration Rate: 3%
