OVERVIEW

Premium Versatility with Walter HP Combo Wheels

The Walter 08B402 HP Combo Wheel represents a significant leap in abrasive technology, specifically designed to bridge the gap between dedicated cutting wheels and grinding discs. Measuring 4 inches in diameter with a 1/8-inch thickness and a 5/8-inch arbor, this wheel is engineered for the professional fabricator who demands efficiency without compromising on safety or performance. In the fast-paced environment of industrial maintenance and metal fabrication, the time spent changing out accessories on an angle grinder can accumulate into substantial lost productivity. The HP Combo wheel solves this by offering a single, robust solution capable of performing multiple tasks effectively.

Constructed with a proprietary bonding matrix, the HP Combo wheel is built to endure the rigors of off-hand cutting, grooving, notching, and light grinding. Unlike standard cut-off wheels, which can be dangerous if used for side-loading or grinding, the HP Combo is reinforced to withstand the lateral forces encountered during shaping and deburring operations. This makes it an indispensable tool for complex jobs where a user might need to cut a piece of stock to length and immediately deburr the edge or grind a bevel for welding. The 1/8-inch profile provides enough rigidity for these grinding tasks while remaining thin enough to slice through steel and stainless steel with impressive speed.

Safety is paramount in abrasive applications, and Walter Surface Technologies has designed this wheel to meet the highest safety standards. The depressed center (Type 27) configuration allows for flush cutting and better access in tight corners, while the reinforced structure resists breakage. Whether you are working on mild steel structural components or precision stainless steel parts, the 08B402 delivers consistent results, maintaining its cutting edge longer than many competitor wheels. This longevity translates to fewer wheel changes, lower consumable costs, and a safer work environment.

For industrial supply procurement, stocking the Walter HP Combo wheel offers a versatile inventory solution. It reduces the need to carry excessive quantities of separate cutting and grinding SKUs for 4-inch grinders. Its broad application range—from pipeline construction to general repair—ensures it meets the needs of a wide variety of end-users. Trust in the reliability of Walter's engineering to provide a wheel that cuts freely, grinds smoothly, and lasts longer.

FAQ

Yes, the HP Combo wheel is reinforced to handle side pressure, making it safe for light grinding, deburring, and notching. However, for heavy stock removal over large areas, a dedicated 1/4" grinding wheel may be more efficient.

The 08B402 is designed for use on both steel and stainless steel. It is formulated to cut quickly and grind smoothly on these metals without contaminating stainless steel.

Absolutely. The 1/8" thickness and reinforced design make it an excellent cutting wheel that is significantly more durable than standard thin cut-off wheels.

This wheel is 4 inches in diameter with a 5/8-inch arbor hole, designed to fit standard 4-inch portable angle grinders.

No, this is a bonded abrasive Type 27 wheel. It mounts directly to the grinder using the standard flange and nut; no backing pad is required.

The maximum safe operating speed is typically around 15,300 RPM for 4-inch wheels, but always verify the RPM rating printed on the actual wheel before use.

A Zipcut is thinner (usually 3/64" or 1/32") and designed purely for fast cutting. The HP Combo is thicker (1/8") to allow for both cutting and grinding. Use Zipcut for speed, use HP Combo for versatility.

This is a Type 27 (depressed center) wheel, which allows the locking nut to sit flush or recessed, permitting grinding at flatter angles.
