- Cap screw counterbores are tools that are used to create a recess in a workpiece for the head of a cap screw. You might use a cap screw counterbore when you need to attach a component to your workpiece using cap screws, and the component has a thickness that is greater than the length of the cap screw.
- Another reason you might use a cap screw counterbore is if you want to create a flush or countersunk appearance for the heads of the cap screws on your workpiece. A cap screw counterbore allows you to create a recess in the workpiece that is sized to fit the head of the cap screw, giving the screw a flush or countersunk appearance.
- Overall, cap screw counterbores can be useful when you need to attach components to a workpiece using cap screws, or when you want to create a flush or countersunk appearance for the heads of the cap screws on your workpiece.
- Versatile Range: Covers screw sizes #6 to 1/2 and M3 to M12, suitable for diverse machining tasks.
- Precision Engineering: Features 3-flute, high-speed steel construction for efficient material removal and longevity.
- Adaptable Fit: Straight shank design ensures compatibility with a wide range of drilling and milling machines.
- Comprehensive Set: Includes pilot diameters from 0.16/3.4mm to 17/32/14mm and cutting diameters up to 25/32/20mm.
- Size Variety: Shank diameters range from 7/32 to 3/4 (inch) and 7/32 to 5/8 (metric), with overall lengths of 3 to 7-1/2.
