Cordial Mart 2Pcs HSS Countersink Drill Bit Set 1/2" 5/8" 82 Deg for Metal
About this item
- Premium High-Speed Steel Construction Crafted from industrial-grade high-speed steel (HSS), these countersink bits deliver exceptional durability and long-lasting sharpness. The robust material resists wear and deformation even under sustained metalworking use, ensuring consistent precision over an extended service life.
- Two Practical Sizes Included This set features two widely used countersink diameters: 1/2 inch (1.27 cm) and 5/8 inch (1.59 cm). Covering most standard screw sizes and common metalworking requirements, this dual-size set removes the need for multiple individual bit purchases.
- Precision 82-Degree Cutting Angle Machined to an exact 82-degree cutting angle, these bits create clean, uniform recesses that allow screw heads to sit perfectly flush with metal workpieces. The precise geometry delivers a smooth, burr-free finish for a professional result on every application.
- Hex Shank with Efficient Chip Evacuation The hex shank design provides a secure, non-slip fit in standard drill chucks and impact drivers, ensuring stable, controlled operation. Milled cutting edges and optimised flute geometry enable smooth chip removal, preventing clogging and overheating during use.
- Versatile Metalworking Applications Suitable for a full range of metal fabrication tasks including countersinking, deburring, chamfering and edge finishing. Compatible with common metal surfaces such as steel and aluminium, ideal for both professional workshop use and home DIY metal projects.
