Sanding paper Makita D-58578 K40 — abrasive sheets for wood, grit K40

Makita D-58578 K40 sanding paper is a set of coarse abrasive sheets intended for woodworking tasks that require rapid material removal. The K40 grit provides aggressive cutting action to shape, level and strip old finishes and surface imperfections before progressing to finer abrasives. These sheets are designed for use with compatible sheet sanders or for manual sanding, offering durable abrasive performance on soft and hardwoods.

Advantages

The coarse K40 grit delivers fast stock removal while maintaining consistent abrasive performance across the sheet. Durable backing ensures good stability and resistance to tearing during both machine and hand sanding. The abrasive grain is formulated to cut wood fibers efficiently, reducing clogging and enabling longer usable life compared with generic papers of similar grit. Sheets are easy to fit on compatible pad systems and provide predictable results when preparing surfaces for subsequent sanding and finishing.

Suitable for

• Shaping and rapid material removal on softwood and hardwood
• Stripping old paint, varnish or adhesive residues
• Leveling uneven joints, edges and rough-cut surfaces
• Initial sanding stage before using finer grits

Key specifications

• Abrasion class: coarse (K40 grit)
• Sheet format suitable for most sheet sanders and manual use
• Backing: tear-resistant paper backing for stability during use
• Abrasive grain: designed for efficient cutting in wood materials
• Application material: intended primarily for wood and wood-based substrates

How to use

Select the K40 sanding sheet and fit it securely to the sanding pad or hold it firmly when sanding by hand. When using a power sander, ensure the sander is compatible with sheet format and operate at the manufacturer’s recommended speed. Move the sander in steady, overlapping passes along the grain where possible to achieve an even surface. Apply moderate pressure—allow the abrasive action to do the work rather than forcing the tool. Replace the sheet when the abrasive becomes clogged or worn to maintain consistent performance.

Usage recommendations

Begin with K40 for heavy material removal, then progress through progressively finer grits to achieve a smooth finish; use appropriate dust extraction and respiratory protection when sanding wood and old finishes.
