135 DEGREES SPLIT POINT and PRECISION FLUTES: 135 degrees split point and twist design prevent "Walking", reduce logging, and penetrate hard material without a pilot hole. Precision fully ground cutting edges and flutes increase cutting speed and clear chips quickly to extend drill bit working life.

SET SIZES INCLUDE: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", 17/64", 9/32", 19/64", 5/16", 21/64", 11/32", 23/64", 3/8", 25/64", 13/32", 27/64", 7/16", 29/64", 15/32", 31/64" and 1/2". (1/16" to 1/2" in 1/64" increments).

【DURABLE】Bonded with corundum and white alundum grain and reinforced by double fiberglass meshes, these cutting discs perform great cutting speed and working life. And they are also strong from shattering and wearing. No debris when broken or damaged ensures safe operations. Grinder wheels adopts 46# raw material sand, cutting surface will be smooth and clear, no damage to the work piece. HIGHFIRE cut off wheels are extremely durable with 2.5 times of service life than the conventional brands.

【PERFORMANCE】0.045" thin cutting wheel design for fast burr free cutting. Perfectly compatible with all 4-1/2 inch angle grinders with 7/8 inch arbor, operating up to 13,300 RPM and 80M/S. Low cutting noise and comfortable hand feeling. Each cutting piece is supplemented with moisture-proof fiber cloth to ensure that its performance is not affected by moisture or corrosion.

【MULTIPLE USES】Tough abrasive cutting discs are perfect for super-fast, clean cutting in carbon steel, stainless steel, iron, copper and other ferrous metals. Those angle grinder cutting wheels can be used on rebar, steel pipe, structural & galvanized steel, sheet metal, structural tubing and black steel. Efficient grinder cutting wheels are used in shipbuilding engineering, factory workshops, valve factories, power generation industry and automobile maintenance.
