Rotary Tool Grinding/Sanding Supply DEDRA 07F091B Wood 8mm Shank

The DEDRA 07F091B rotary tool grinding/sanding supply for wood is a replaceable accessory designed for detailed sanding and grinding on wooden surfaces. With an 8 mm shank and a 13 mm working diameter, this accessory fits rotary tools that accept an 8 mm shank and is intended to deliver controlled material removal on contours, edges, and small workpieces. The product is suitable for tasks that require precision on wood, such as shaping, deburring, smoothing joints and preparing surfaces for finishing.

Advantages

This sanding/grinding supply provides consistent contact with wooden surfaces thanks to its defined working diameter, enabling accurate shaping and finish preparation. The 8 mm shank ensures a stable hold in compatible chucks or collets, reducing runout and vibration during operation. Its compact working size allows access to tight areas and fine detail work while maintaining predictable cutting or abrasive action for repeatable results.

Suitable for

• Detail sanding and shaping of wooden models and prototypes
• Edge smoothing and deburring of small wooden parts
• Surface preparation before staining, painting or varnishing
• Restoration and repair of furniture details and mouldings

Key specifications

• Shank diameter: 8 mm
• Working diameter: 13 mm

How to use

Install the accessory securely into a rotary tool collet or chuck that accepts an 8 mm shank. Verify the bit is seated fully and tighten the tool’s collet or chuck according to the rotary tool manufacturer’s instructions. Start the tool at a low speed to check balance and runout, then increase speed to the recommended range for wood sanding or grinding. Apply light, steady pressure and let the accessory perform material removal; avoid forcing the bit to prevent overheating or premature wear. Periodically inspect the accessory for wear and replace when abrasive performance diminishes.

Usage recommendations

Use appropriate personal protective equipment—eye protection, dust mask and hearing protection—when operating the rotary tool. Match rotary speed and feed to the wood type and the amount of material to be removed. For prolonged use, allow intermittent cooling pauses to extend the life of the accessory and prevent damage to the workpiece.
