3M™ 60440226755 Cross Pad 341D 2"W x 2"L x 1/2" Thick 80 Grit

Description

3M™ cross pad 341D 2" x 2" x 1/2" aluminum oxide 80 grit

3M™ cross pad 341D is used for close tolerance polishing of small radii and channels deburring the ends and insides of tubing and other special applications. When inserted into a hole or channel the flexible cross shape conforms to the diameter of the workpiece making this a versatile accessory for your inside diameter finishing jobs.

The x-weight cloth backing of 3M™ cross pad 341D supports both grinding and polishing applications. It has a closed coat of aluminum oxide abrasive secured with a heat-resistant resin bond. This cross pad works well where close-tolerance polishing or deburring is needed.

A cross pad attaches to a threaded mandrel (sold separately) that attaches to a rotary tool such as a die grinder or drill. Together the mandrel and cross pad enable the user to grind or finish the inner contours of various-sized channels. Max RPM depends on the size of the pad.

Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough durable abrasive that self-fractures to expose fresh cutting edges whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate hardness and strength it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking including ferrous alloys.

Resin adheres the abrasive particles to the cloth backing creating a strong stiff bond that withstands the high heat and pressure of heavy sanding.
