3M 7000119797 Abrasive Sheet 40 Grit 2-3/4 X 16-1/2 in

Product Description

The 3M 7000119797 is an aluminum oxide abrasive sheet designed for sanding and shaping tasks common in automotive bodywork. Rated at 40 grit, it is suited for aggressive material removal on substrates such as primer, paint, plastic filler, and fiberglass. The sheet measures 2-3/4 inches by 16-1/2 inches and uses a hook-and-loop (Hookita) backing that allows fast attachment and removal from compatible hand blocks or power tools. Auto body technicians reach for this sheet when feather-edging, shaping body filler, or prepping bare panels before primer application.

This sheet is intended for professional automotive repair environments where substrate prep quality directly affects finish results. The 40-grit cut makes it appropriate for early-stage material removal passes rather than finish sanding. Its hook-and-loop backing enables transitions between hand sanding and machine use without changing the abrasive, supporting workflow efficiency on production-style repair jobs.

Key Features

• 40-grit aluminum oxide construction for aggressive stock removal
• Hook-and-loop backing compatible with 3M Hookita attachment system for tool-free swaps
• Sheet size of 2-3/4 inches x 16-1/2 inches fits standard long-board hand blocks and compatible orbital tools

Compatibility

Designed for use with 3M Hookita-compatible hand blocks and power sanding tools that accept hook-and-loop abrasive sheets in the 2-3/4-inch x 16-1/2-inch format.

Installation Notes

Auto body technicians should confirm the backing pad or sanding block is clean and free of debris before attaching the sheet to ensure full hook-and-loop engagement. Always work in a well-ventilated area and wear appropriate respiratory protection when dry-sanding automotive coatings or fillers. Disconnect or power down any pneumatic or electric sanding tool before changing abrasive sheets. Inspect the sheet for loading or glazing and replace when cut rate noticeably drops.
