DIABLO TYPE 1 THIN KERF METAL CUTTING DISCReinforced aluminum oxide cutoff wheel for handheld angle grinders. The thin .040" kerf removes less material per pass, which means the grinder spends its watts cutting rather than pushing - a clean, fast slice through steel rod, threaded rod, sheet metal, EMT, structural angle, and rebar with noticeably less heat blueing at the cut than a standard 1/8" wheel.
- 5" outer diameter, .040" thin-kerf, 7/8" arbor
- 12,200 max RPM - matches a 5" angle grinder
- Type 1 (flat) profile for straight cutoff work, not grinding
- Premium aluminum oxide grain in fiberglass-reinforced binder for steel, stainless, cast iron, angle iron, rebar, steel studs, and sheet metal
- Lower amp draw than a thick wheel - the grinder holds RPM through the cut
- Manufacturer Part Number: DBD050040101F
Selection Tip: 5" is a less common grinder size and is mainly chosen when the matching 5" tool is already in the shop (some Bosch, Metabo, and pneumatic cutoff models) or when the user wants slightly more cut depth than a 4-1/2" disc without stepping up to a heavier 6" grinder. Will not fit a standard 4-1/2" angle grinder guard.
Use Tip: Let the disc come to full RPM before contact, hold a steady angle, and use light pressure - pushing harder loads the disc and burns the binder. Cut on the back half of the wheel (not the leading edge) for the cleanest line, and never side-load a Type 1 disc; thin-kerf wheels are made for cutting only, not edge grinding.
Safety: Always use the guard, full face shield, hearing protection, and leather gloves. Inspect the disc for cracks before mounting; retire any wheel that has been dropped or that shows a chipped edge.
