Accusize HSS Countersink, 1-1/2in, 90 Degree, 3-Flute, 3/4in Weldon Shank
- 1-1/2IN, 90-DEGREE CUTTING PROFILE: Three flutes cut a countersink up to 1-1/2in in diameter at a 90-degree included angle (45 degrees per side)
- 3/4IN WELDON SHANK: Fits a holder designed for a 3/4in Weldon shank. A different spindle interface requires a suitable adapter
- BUILT FROM HIGH-SPEED STEEL: HSS offers good wear resistance for general-purpose countersinking, chamfering, and deburring on ferrous and nonferrous materials
- DEBUR AND CHAMFER IN ONE PASS: Purpose-built for deburring and chamfering pre-drilled holes, leaving a clean, precise finish without a second tool
- CHECK THE CUTTER DIMENSIONS: 1-1/2in large-end diameter (D), 5/16in small-end diameter (d1), 3/4in Weldon shank (b), 2-1/16in overall length (L), and 90-degree included angle. Match the finished countersink diameter and angle to the fastener drawing

3-flute countersinks are the go-to choice for achieving a chatter-free, professional finish. Unlike single-flute designs, the triple-edge geometry provides superior stability and balanced cutting forces, which significantly reduces vibration. This ensures perfectly round, smooth holes in tougher materials like steel or aluminum. Their ability to clear chips efficiently prevents clogging and heat buildup, extending tool life while making them ideal for high-speed production environments.
Smooth Chamfering
3-flute countersinks provide smooth chamfering by maintaining balanced cutting forces across multiple edges, reducing vibration and tool deflection. This stability allows for consistent material removal, improved surface finish, and reliable performance across a range of materials, especially steels and harder alloys, making them a versatile choice for both precision work and production environments.
HSS is a dependable standard for steel, delivering consistent cutting performance, durability, and long tool life.
Ideal for softer metals, for example aluminum, brass and copper. Bright finish helps reduce sticking and galling, producing smooth, clean chamfers.
Cuts easily through hardwoods and softwoods without overheating, making it ideal for clean chamfers and screw prep.
Suitable for a wide range of plastics and composites, delivering smooth, precise cuts with minimal burring.
The 3-flute countersink offers the best balance of stability, finish, and speed. It cuts faster and more consistently than 0 and single-flute tools while maintaining good chip evacuation. Compared to 6-flute designs, it needs less rigidity and resists clogging, making it versatile and easy to use.
