Product Description
CMT 180 Grit 3-5/8" Perforated Aluminum-Oxide Delta Sandpaper for Wood is a 10-piece pack of precision abrasive sheets engineered for fine sanding of wood surfaces and wood-based panels. Designed to fit delta-profile sanding pads, these perforated sheets combine aluminum-oxide abrasive grain with a full resin bond to deliver consistent, high-performance material removal across a wide range of woodworking tasks - from smoothing rough lumber to finishing chipboard and plywood.
Key Features
- 180 Grit Aluminum-Oxide Abrasive Grain - delivers fine-level sanding for smooth, even surface preparation without over-removing material from delicate wood surfaces.
- Full Resin Bond Construction - secures abrasive grain firmly across the sheet, maintaining high abrasion performance and extending the usable life of each sheet.
- Perforated Delta Design - holes align with the sanding pad to allow dust extraction during operation, keeping the work surface cleaner and improving sanding visibility.
- 93mm (3-5/8") Delta Profile - triangular sheet shape reaches into corners and tight spaces that flat or rectangular pads cannot access, making it effective for detail and finish work.
- 10-Piece Pack - provides multiple sheets in a single purchase, reducing downtime from frequent resupply during extended sanding projects.
Why This Product
- The combination of aluminum-oxide grain and full resin bond means these sheets hold up to repeated use on demanding materials like chipboard, plywood, and construction boards - not just finished timber - making them a practical choice for both rough pre-sanding and finishing stages.
- The perforated delta format addresses two common sanding frustrations at once: dust accumulation on the work surface and difficulty reaching corners - so woodworkers spend less time cleaning up and more time achieving a quality result.

Frequently Asked Questions
What types of materials can these delta sanding sheets be used on?
These 180 grit aluminum-oxide sheets are suitable for sanding all types of woods, chipboard, plywood, and construction boards. They are also appropriate for pre-sanding rough, uneven beams and boards where surface leveling is needed before a finer finish pass.
Why does the 180 grit designation matter for woodworking projects?
A 180 grit rating places these sheets in the fine abrasive range, making them well-suited for finish-level sanding passes after coarser grits have addressed major surface irregularities. The aluminum-oxide abrasive grain and full resin bond work together to provide high abrasion performance while leaving a smooth surface ready for finishing.
What is the purpose of the perforations in these delta sanding sheets?
The perforated design allows dust to be extracted through the sanding pad during use. This helps keep the work surface clearer of debris, reduces clogging of the abrasive surface, and supports a cleaner, more efficient sanding process.
