3M 7100142738 | 0.500" Diameter x 1.500" OAL x 60 Grit Ceramic Taper Cartridge Roll

Description

The 3M 7100142738 747D cartridge roll is a precision ceramic abrasive made for fast material removal and reproducible finish control on metal components. This 0.500" diameter by 1.500" overall length cartridge roll delivers aggressive 60-grit cutting for shaping, grinding, and edge work in confined geometries. Constructed with durable ceramic cloth backing, the 3M Cartridge Roll 747D resists glazing and maintains cut consistency through extended tool cycles. Tapered cartridge geometry fits standard mandrel-type holders for die grinders and rotary finishing tools, enabling fast installation. Designed for finishing, polishing, grinding, and deburring, the roll supports both hand-held and machine-mounted operations in production cells. Closed-coat ceramic abrasive provides a highly effective cutting area to remove stock quickly while preserving part form. X-weight cloth backing balances flexibility and tensile strength so the cartridge roll tracks true under light-to-moderate pressure. The 60-grit specification is optimized for medium-to-heavy material removal without sacrificing surface integrity on steels and alloys. Compatibility with common mandrel tool abrasive roll fixtures reduces changeover time and simplifies tool inventory. The 3M 747D performs reliably in intermittent coolant use but also delivers consistent dry-cut results for shop-floor flexibility. Operators will find predictable wear characteristics that simplify process planning and minimize unexpected downtime. This cartridge roll is a compact solution when access is limited and a standard disc or belt cannot reach the work area. Manufacturers use the 3M 7100142738 to reduce hand-finishing time and to improve dimensional consistency on small assemblies. Robust bond chemistry and ceramic mineral selection give the roll a long useful life versus conventional abrasives at comparable grit. For detail grinding where throughput and repeatable finish matter, the 3M Cartridge Roll 747D is a dependable industrial accessory.

Product Features and Benefits

Precision Taper Cartridge Geometry

Tapered 0.500" × 1.500" form provides access to tight radii and internal features, making the 3M 7100142738 ideal for detail grinding.

Ceramic Cloth Abrasive

Ceramic mineral on a cloth backing extends cut life and resists glazing for consistent performance across multiple parts with the 3M 747D.

60 Grit for Aggressive Stock Removal

The 60 grit balance removes material quickly while controlling surface finish, reducing downstream handwork and cycle time.

Mandrel-Compatible Mounting

Designed for standard mandrel tool abrasive roll systems, the cartridge rolls install rapidly on die grinders and rotary tools.

Closed-Coat Construction

Closed-coat abrasive increases cutting area to improve material removal rates and reduce the number of passes required per part.

Frequently Asked Questions

What is the 3M 7100142738 cartridge roll best used for?

The 3M 7100142738 is best for detail grinding, deburring, edge preparation and localized stock removal in confined or hard-to-reach areas.

Which tool mounts work with the 747D cartridge roll?

The 3M Cartridge Roll 747D fits standard mandrel holders and die grinders designed for tapered cartridge-style abrasive rolls.

Can this ceramic cartridge roll be used for hardened steels and tool steels?

Yes, the ceramic mineral formulation gives the 747D strong cutting action suitable for steels and many hard alloys when used with appropriate feed and coolant practice.

How does the 60 grit cartridge roll compare to standard 60 grit sandpaper discs?

The 3M 747D cartridge roll provides more conformal access and a longer useful life in confined profile work than a flat 60 grit sandpaper disc.

Is the 3M 747D considered an industrial abrasive accessory compatible with mandrel tool setups?

Yes, the cartridge roll is a common industrial abrasive accessory used on mandrel tool abrasive roll fixtures for targeted finishing and grinding tasks.
