M-42 cobalt steel construction with 8% cobalt alloy for 30% higher drilling speed. High performance cutting effectively removes auto body panel spot welds. Special spur point design cuts through one panel while leaving the second intact. New type 2 point design offers longer life and chip resistance. Gold finish ensures long wearing cutting edges. Versatile for use in all standard drill chucks. MADE IN THE U.S.A.

M-42 cobalt steel construction with 8% cobalt alloy allows 30% higher drilling speed. High performance cutting effectively removes auto body panel spot welds. Special spur point cuts through one panel, leaving the second intact. Extended length twin end models cut twice as many spot welds. Gold finish provides long wearing cutting edges. MADE IN THE U.S.A.

SOLID CARBIDE construction ideal for Boron steel and high strength alloys. ALUMINUM TITANIUM NITRIDE (AlTin) COATING offers high heat resistance and lubricity for dry use. TRIPLE FLUTE DESIGN enhances cutting efficiency by 50%. Micro-grain carbide ensures long service life. Compatible with standard variable speed drill motors. MADE IN THE U.S.A.

M-42 cobalt steel construction with 8% cobalt alloy allows 30% higher drilling speed for fast job completion. High performance cutting effectively removes auto body panel spot welds. Special spur point cuts through one panel, leaving the second intact. Gold finish provides long wearing cutting edges. Versatile for all standard drill chucks, including air powered drill motors. MADE IN THE U.S.A.

M-42 cobalt steel construction with 8% cobalt alloy for 30% higher drilling speed. TiN coating for extended service life and lubricity. Designed for high strength alloy steels, including Boron steel. Special spur point cuts through one panel, leaving the second intact. New type 2 point design for longer life and chip resistance. Requires slower speed (490 RPM Max) than standard drills (1800 RPM). MADE IN THE U.S.A.

Designed for auto body work, these M‑42 cobalt bits remove spot welds quickly. They’re 30% faster thanks to 8% cobalt alloy, and the special spur point cuts one panel cleanly. Twin-end designs offer twice the service life. Ideal for standard or air drill motors, the gold finish reduces wear. This 4-piece kit covers 5/16" & 3/8" single/twin ends. Made in the USA for fast, effective panel separation.
