YG8 Alloy Cutter Head — WearResistant Countersink and Drilling Insert Key benefits Durable cutting life: YG8 alloy construction resists wear for longer service between tool changes. Consistent results: Precision ground cutting edges deliver accurate countersinks and clean hole openings. Low maintenance finish: Surface spray treatment and oxidation improve corrosion resistance and reduce buildup. Flexible sizing: Complete specifications available across a 2.8–4.0 mm drilling diameter range for smalldiameter work. What it does Designed for countersinking and hole opening in wood and aluminum alloy. Provides stable, repeatable performance for smalldiameter drilling and chamfering tasks. Important attributes Material: YG8 alloy cutter head for enhanced wear resistance. Surface: Spraytreated and oxidized finish for improved durability and corrosion resistance. Sizes: Full specification range from 2.8 mm to 4.0 mm drilling diameter to match common smallhole requirements. Function: Countersinking and opening (drilling) in wood and aluminum alloy materials. Why customers choose it Reduces rework by producing clean, accurate countersinks and holes. Cuts toolchange frequency thanks to the wearresistant YG8 alloy. Compatible with applications that require controlled, smalldiameter countersinks or pilot holes in wood and aluminum alloy. Typical applications Cabinet and furniture assembly: Create precise countersunk holes for screw heads in hardwood and plywood. Lightweight metal fabrication: Produce clean countersinks and entry holes in aluminum alloy parts before fastening. Joinery and trim work: Drill small, accurate openings and chamfers for hinges, fittings, and fasteners. Ordering notes Available in complete sizes from 2.8 mm to 4.0 mm drilling diameter. Surfacetreated and oxidized for extended life and consistent performance.
