Sanding brush Makita D-73346 Carbon steel 7.5 cm 12500 RPM

The Makita D-73346 sanding brush is a carbon steel accessory for rotary tools, designed for sanding, surface preparation and light deburring. With a 7.5 cm diameter and 0.3 mm wire thickness, the brush provides consistent contact with work surfaces while maintaining durability under rotational loads. Its maximum rated speed of 12,500 RPM matches common rotary tool operating ranges, enabling efficient material removal on metal, wood and composite surfaces when used according to tool specifications.

Advantages

The carbon steel construction offers a balance of stiffness and resilience, giving repeatable abrasion performance and a longer service life compared with softer wire types. The 7.5 cm diameter provides good coverage for medium-sized areas while remaining manageable for precision work. A wire thickness of 0.3 mm helps preserve shape during use and delivers uniform sanding without aggressive gouging when used appropriately. The brush is compatible with many rotary tool chucks that accept this accessory size and speed rating.

Suitable for

• Removing rust, scale and loose paint from metal surfaces
• Light deburring of edges after cutting or machining
• Surface preparation before painting or coating
• Cleaning weld seams and smoothing small imperfections

Key specifications

• Material: carbon steel wire
• Diameter: 7.5 cm
• Wire thickness: 0.3 mm
• Maximum rotational speed: 12,500 RPM
• Suitable for handheld rotary tools and bench-mounted rotary devices that accept this accessory size

How to use

Fit the sanding brush to a rotary tool that supports the accessory diameter and speed rating, ensuring the tool is switched off and unplugged or the battery is removed before installation. Secure the brush according to the tool manufacturer’s instructions, check for runout and spin freely by hand to confirm correct mounting. Operate the tool at speeds not exceeding 12,500 RPM and apply light to moderate pressure, allowing the brush to do the cutting action; excessive force may deform the wires or reduce tool control. Keep the brush moving across the surface to avoid creating grooves or uneven wear.

Usage recommendations

Wear appropriate personal protective equipment: safety goggles, gloves and a dust mask. Use the brush on clean, stable workpieces clamped or supported to prevent movement. Avoid using the brush on brittle materials where wire contact could cause damage. Inspect the brush regularly for wire breakage or uneven wear and replace it if performance declines or safety is compromised.
