OVERVIEW

Precision Grinding for Demanding Industrial Applications

The Walter A-32 Mounted Point (SKU: 12D091) represents the pinnacle of abrasive engineering for precision metal removal. Designed specifically to address the challenges of working with tough steel, tool steel, and cast iron, this mounted point is an essential consumable for tool and die makers, fabricators, and MRO professionals. Unlike generic abrasive stones that may suffer from eccentricity or inconsistent grain structure, Walter Surface Technologies manufactures these points with a rigorous focus on balance and concentricity. This attention to detail ensures that the point runs true at high RPMs, protecting both the workpiece from chatter marks and the die grinder bearings from premature wear.

The abrasive composition of the 12D091 is formulated to maintain a sharp cutting edge even when processing high-tensile materials. The vitrified bond holds the abrasive grains securely, allowing them to fracture at the optimal rate to reveal fresh cutting surfaces. This self-sharpening action is critical when grinding hard alloys, as it prevents the glazing that often leads to excessive heat buildup and surface discoloration. The A-32 shape—a conical profile with a rounded nose—is particularly versatile, allowing operators to reach into bores, blend contours, and deburr complex geometries where larger wheels cannot reach.

Safety and comfort are paramount in manual grinding operations. The superior balance of Walter mounted points translates directly to reduced vibration transfer to the operator's hand. This reduction in vibration not only improves the surface finish quality but also significantly reduces the risk of Hand-Arm Vibration Syndrome (HAVS) during prolonged use. Whether used for enlarging holes, fitting mechanical parts, or general finishing in confined spaces, the Walter A-32 mounted point delivers consistent, high-performance results that industrial environments demand.

Integration into your existing workflow is seamless, thanks to the standard shank sizing and robust construction. When precision, longevity, and surface integrity are non-negotiable, the Walter A-32 stands out as the professional's choice for mounted abrasive solutions.

FAQ

The A-32 shape is a conical or bullet-shaped point with a rounded nose, ideal for grinding in holes, corners, and contoured surfaces.

This point is specifically formulated for 'Tough Steel', making it suitable for steel, cast iron, tool steel, and high-tensile alloys.

This mounted point is designed for use with a die grinder (pneumatic or electric) equipped with a collet that matches the shank size (typically 1/4 inch).

Proper balance prevents vibration and runout. This ensures a smoother finish, extends the life of the grinder's bearings, and reduces operator fatigue.

While it can grind aluminum, it is not optimized for it. Soft metals like aluminum may clog (load) the abrasive grains. A point specifically designed for non-ferrous metals or the use of a lubricant is recommended for aluminum.

It features a vitrified bond, which is a glass-like bond that provides high rigidity and excellent shape retention for precision grinding.

The maximum safe RPM depends on the size of the head and the overhang (how far the shank sticks out of the collet). Always refer to the package rating and ANSI B7.1 safety standards. Generally, reduce speed as overhang increases.
