3M 7000121917 | 877024 0.250" OAL Aluminum Oxide Medium Mounted Point

Description

The 3M 7000121917 Aluminum Oxide Mounted Point is a compact, unitized mounting point made for precise deburring, blending, and finishing of small workpieces. This 0.25" OAL unit, designed for die grinder mounted point applications, is made of medium-grade aluminum oxide mineral bonded into a dense, unitized structure that self-dresses to expose fresh abrasive grain at all times. The 3M Unitized Mounted Point removes burrs, flash, and minor weld irregularities from metals and some plastics while maintaining part geometry. Its shaft attachment allows for secure, high-speed operation in handheld die grinders and pneumatic tools, resulting in consistent results over repeated operations. Medium grade (blue) is color-coded for easy identification on busy shop benches, reducing selection errors. The unitized construction improves cut consistency compared to loose non-woven wheels and increases usable life under normal operating conditions. Use the 3M 7000121917 for precise deburring and repeatable surface conditioning to reduce rework and increase throughput.

Product Features and Benefits

Unitized aluminum oxide for consistent performance

Compressed, cured, unitized construction exposes fresh mineral as the product wears, delivering steady cutting action and predictable finish for deburring and blending tool tasks.

0.25" overall length for tight access

The short, compact profile lets operators reach small cavities and hard-to-access features without altering part geometry—ideal for precision die grinder mounted point work.

Medium grade (blue) for general-purpose finishing

The 3M Unitized Mounted Point’s medium abrasive aggressiveness balances cut rate and surface refinement, making it suitable for blending, light stock removal, and final cleanup steps.

Shaft-mounted for secure high-speed use

The 3M Aluminum Oxide Mounted Point features a rigid metal spindle attachment that provides stable mounting in die grinders and pneumatic tools, enabling safe operation at recommended RPMs with minimal runout.

Resists smearing, cleaner surfaces, less rework

Aluminum oxide abrasive chemistry and an open unitized web reduce loading and smearing on softer substrates, helping operators achieve cleaner surfaces faster.

Color-coded for quick selection

Blue medium-grade coding simplifies inventory handling and speeds technician selection in production or repair environments.
