3/8" KEYSCO Spot Weld Cutters, High Speed Steel for sale Supply

The 3/8" KEYSCO high-speed steel spot weld cutter drills through 3/8" factory resistance spot welds on automotive panels, cleanly separating the top panel from the underlying structure without damaging the base sheet metal.

Many factory spot welds on passenger vehicles and light trucks fall in the 5/16" to 3/8" diameter range, making 3/8" one of the most commonly needed cutter sizes in a collision repair shop. Keeping a sharp 3/8" cutter on hand covers a wide range of repair scenarios.

KEYSCO produces professional collision and autobody tools to exacting standards. Their spot weld cutters feature precision-ground HSS blades, consistent dimensions, and quality that meets the demands of professional collision repair environments used daily.

Maximize HSS cutter life by using the correct RPM (400–600), applying cutting oil before each cut, keeping drill pressure moderate and steady, and cleaning metal chips frequently. Avoid running the cutter dry on hard steel, which rapidly dulls the cutting edges.

Yes. The 3/8" KEYSCO spot weld cutter can cut through double-layer weld flanges (two panels joined by spot welds) as found on door pillars, rocker panels, and roof rails. Drill depth must be controlled to cut through both layers without entering the structural member.

A spot weld cutter starter kit typically includes multiple cutter sizes (1/4", 5/16", 3/8", 1/2") in either HSS or cobalt, plus a centering pilot pin for accurate weld location. KEYSCO and other brands offer complete kits for shops needing full size coverage.
