Product Description
CMT 240 Grit 3-5/8" Perforated Aluminum-Oxide Delta Sandpaper for Wood is a precision abrasive sheet designed for ultra-fine finishing on wood and wood-derived materials. This 10-piece pack of 93mm delta sanding sheets delivers consistent, high-performance results across a wide range of sanding tasks - from smoothing rough lumber to refining chipboard and plywood surfaces.
Key Features
- 240 grit aluminum-oxide abrasive grain - provides ultra-fine sanding ideal for finish-stage work on wood surfaces, leaving a smooth, refined result.
- Full resin bond construction - secures abrasive grains firmly to the backing, supporting high abrasion performance and longer sheet life during demanding sanding sessions.
- Perforated delta sheet design - holes align with sanding pad dust ports to allow effective dust extraction, keeping the work surface cleaner and improving visibility as you work.
- 93mm (3-5/8") delta format - fits standard delta sanding pads used with multi-cutter oscillating tools, making sheet changes straightforward and compatible with common tool setups.
- 10 pieces per pack - provides a useful quantity for extended projects without frequent restocking interruptions.
Why This Product
- For woodworkers and contractors sanding rough or uneven beams, boards, chipboard, plywood, and construction panels, the aluminum-oxide grain and full resin bond combination means sheets hold up through demanding material removal while still delivering the fine 240-grit finish quality needed for final-stage preparation.
- The perforated design is not just a convenience feature - it actively channels dust away from the sanding surface during use, which reduces clogging of the abrasive and helps maintain consistent cutting performance throughout the life of each sheet.

Frequently Asked Questions
What materials can these delta sanding sheets be used on?
These 240 grit aluminum-oxide delta sheets are suitable for sanding all types of woods, chipboard, plywood, and construction boards. They are also appropriate for pre-sanding rough and uneven beams and boards where a finer finish is needed after initial material removal.
Why does the 240 grit rating matter for my project?
Grit 240 falls in the ultra-fine range, making these sheets best suited for finish-stage sanding rather than aggressive stock removal. At this grit level, the aluminum-oxide abrasive smooths the wood surface in preparation for staining, painting, or applying a topcoat - rather than reshaping or leveling the workpiece.
Do the perforations affect sanding performance?
The perforated pattern is designed to work with the dust extraction ports in compatible delta sanding pads. When connected to a vacuum or dust extraction system, the holes allow fine wood dust to be pulled through the pad rather than accumulating on the surface. This helps keep the abrasive from loading up prematurely and maintains more consistent cutting action throughout each sheet's use.
