Product Description
CMT 80 Grit 3-5/8" Perforated Aluminum-Oxide Delta Sanding Sheets are designed for effective stock removal and pre-sanding on a wide range of wood-based materials. These triangular abrasive sheets bring aggressive 80 grit cutting action to detail sanding tasks, making them a practical choice for tradespeople and woodworkers tackling rough surfaces, uneven beams, chipboard, plywood, and construction boards. The full resin bond and aluminum-oxide abrasive grain work together to deliver consistent, high-abrasion performance throughout the life of each sheet.
Key Features
- 93mm (3-5/8") Delta Profile: the triangular shape fits detail sanders and multi-cutter sanding pads, letting you reach into corners and tight areas that flat sheets cannot access.
- 80 Grit Aluminum-Oxide Abrasive Grain: coarse enough for pre-sanding rough, uneven beams and boards, removing material efficiently before finish sanding.
- Full Resin Bond Construction: keeps abrasive grain firmly anchored to the backing throughout use, supporting high abrasion performance and longer sheet life.
- Perforated Design: holes align with the sanding pad to allow dust extraction directly through the sheet, keeping the work surface cleaner and improving visibility of the sanded area.
- Broad Material Compatibility: suitable for sanding all types of woods, chipboard, plywood, and construction boards, reducing the need to switch between specialty sheets for different substrates.
- 10-Piece Masterpack: multiple sheets per pack reduce downtime from frequent restocking on longer sanding jobs.
Why This Product
- When pre-sanding rough lumber, uneven beams, or construction boards, an 80 grit aluminum-oxide sheet with full resin bond cuts aggressively without the abrasive shedding prematurely - getting the surface ready for finish work faster.
- The perforated delta format is purpose-built for detail sanding tools with dust extraction capability, so chips and debris are pulled away from the cut rather than accumulating under the sheet and reducing abrasive contact.

Frequently Asked Questions
What types of wood and wood-based materials are these delta sheets suitable for?
These 80 grit aluminum-oxide delta sheets are suitable for sanding all types of woods, chipboard, plywood, and construction boards. They are specifically noted for pre-sanding rough and uneven beams and boards where aggressive stock removal is needed before finer finish sanding.
Why do the delta sheets have perforations, and does that affect sanding performance?
The perforations are designed to align with the holes on compatible delta sanding pads, allowing dust and debris to be extracted directly through the sheet during sanding. This keeps the work surface cleaner, helps maintain consistent abrasive contact, and contributes to a clearer view of the area being sanded without meaningfully reducing the abrasive surface available for cutting.
How many sheets are included in one pack?
Each masterpack contains 10 perforated aluminum-oxide delta sanding sheets, all at 80 grit, providing a ready supply for extended sanding sessions on wood and wood-derivative materials.
