APWIKOGER 3-Piece Titanium-Coated Sawtooth Countersink Spot Weld Drill Bit Set

Take your metalworking projects to the next level with this professional-grade 3-piece HSS cobalt steel spot weld drill bit set. Available in 6.5mm, 8mm, and 10mm sizes, these titanium-plated sawtooth countersink bits are engineered for clean, efficient removal of sheet metal spot welds — leaving a smooth, professional finish every time. Made in Mainland China.

Key Features

• Titanium-Coated Durability: Constructed from high-speed cobalt steel alloy with a hard-wearing titanium coating, these bits deliver exceptional strength and long service life across repeated use in metalworking applications.
• Precision Sawtooth Point Design: Each bit is machined without burrs, providing a clean, accurate cut. The sawtooth tip geometry ensures precise centering so the bit stays on target — no wandering, no slipping.
• Flat Shaft for Secure Chuck Grip: The flat-sided shaft locks firmly into standard drill chucks, maximizing stability and torque transfer for a controlled, shake-free drilling experience.
• Versatile Multi-Material Use: Designed primarily for sheet metal spot weld removal, these bits also perform on wood and other materials, making them a versatile addition to any workshop or job-site toolkit.
• Compact & Portable: Lightweight and easy to store, this set travels with you wherever the job takes you — from the garage to the fabrication floor.

Frequently Asked Questions

Q: What sizes are included in this titanium spot weld drill bit set?

A: The set includes three sawtooth countersink bits in 6.5mm, 8mm, and 10mm diameters, giving you flexibility for different spot weld sizes and sheet metal thicknesses.

Q: Are these countersink bits compatible with standard power drills?

A: Yes. The flat shaft design is compatible with standard drill chucks found on most corded and cordless power drills, ensuring a secure, wobble-free fit during use.

Q: What materials can these spot weld drill bits cut through?

A: These cobalt steel alloy bits with titanium coating are primarily designed for sheet metal spot weld removal but are also suitable for use on wood and a variety of other materials, making them a versatile choice for metalworking and fabrication tasks.

Q: How does the titanium coating benefit these drill bits?

A: The titanium plating significantly increases the surface hardness and wear resistance of the bit, extending its working life compared to uncoated HSS bits — especially during repeated use on metal surfaces.
