3M Hookit steunschijf 115mm M14 schroefdraad, middelhard, 12500 t/min

A backing pad that prioritises clean release and consistent abrasive contact, this 3M Hookit model stands apart from generic alternatives through its precision-moulded polyurethane core and steel M14 hub. The 115 mm diameter is matched to the most common angle grinder size in metalworking and body repair, while the medium-density face delivers a controlled compromise between conformability and cut. Because the hook-and-loop interface is factory-aligned to 3M Hookit discs, operators avoid the edge lifting and premature wear often seen with mixed-brand combinations.

Highlights

• 115 mm round pad with M14 threaded steel insert for direct mounting on angle grinders and rotary sanders.
• Hookit hook-and-loop face allows fast abrasive changes without tools or adhesive residue.
• Medium-density polyurethane body absorbs vibration and reduces edge gouging on flat and gently curved panels.
• Rated to 12,500 RPM, suitable for high-speed electric and air tools within the pad's safety envelope.
• Semi-rigid flexibility bridges the gap between hard plates and soft interface pads, improving finish consistency.
• Solid design without dust extraction holes, ideal for use with external vacuum shrouds or open-coat abrasives.

In daily use

Mount the pad on any M14-spindle grinder, press a Hookit disc into place, and begin work immediately. The black and blue colour scheme is not cosmetic: the blue face indicates the hook side, helping technicians orient discs correctly in low-light booths. During sanding, the medium-density PU layer dampens chatter and helps the abrasive follow the workpiece rather than skipping over high spots. When the disc is worn, a simple peel-and-replace action keeps downtime to seconds. For polishing or finishing steps, the same pad accepts Hookit surface conditioning discs, reducing the number of tools needed on a job.

Final note

For workshops standardising on 3M Hookit abrasives, this backing pad is the logical foundation: it preserves disc life, improves finish quality, and eliminates the guesswork of mismatched attachment systems.
