It features a 60-degree included angle and a bright uncoated finish. The 1\/2-inch straight cylindrical shank fits standard drill chucks and collet holders. With a 7\/8-inch head diameter and a 0.230-inch tip diameter, this tool delivers clean, consistent entry angles across a wide range of base materials. It is a single-end tool with no pilot, suited for use in manual or CNC drilling setups by machinists, tool-and-die tradespeople, and maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis countersink is intended for general industrial and production use where accurate chamfer angles are required prior to fastener seating or edge finishing. The 60-degree included angle is commonly specified for metric and certain inch-series fastener countersinks. The 6-flute geometry reduces chatter and improves surface finish compared to single- or double-flute designs. It is appropriate for use on alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-nickel steel, high-tensile steel, Monel, and plastic workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree included angle for precise chamfer geometry on a broad range of fastener types\u003c\/li\u003e\n\u003cli\u003e6-flute design reduces chatter and produces cleaner surface finishes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across multiple material types\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with cutting fluids and oils\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical 1\/2-inch shank for broad chuck and collet compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end tool with no pilot — requires accurate centering on a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2-inch drill chucks and collet holders on bench drills, drill presses, and CNC machining centers.
