Power Tool Accessories

Power tool accessories are the add-ons that help your tools do the job right. Things like saw blades, drill bits, and grinding wheels can make or break your project. Accessories need to be authentic and designed specifically for the tool and recommended by the tool manufacturer.

Select the right accessories

Whether you need a bit extension, dust collection attachment, specialty wheel, or hole saw, you should choose accessories specifically recommended by the tool manufacturer for use on its tool.

Just because an accessory can be attached to your power tool, it doesn’t mean it is intended for use on that tool, and it does not ensure safe operation. Speed, size, guarding, application, and mounting requirements must all be addressed. Third-party websites often promote the use of accessories that are inappropriate for a particular tool, often turning it into a tool used for other than its intended purpose. The site may include pictures of accessories mounted on well-known brands of power tools. This does not mean the accessory use is recommended by the manufacturer of the tool.

Always follow these commonsense safety rules:

  • Always read and follow the safety information in the operator’s manual of the power tool.
  • Only use accessories recommended in the operator’s manual for the power tool.
  • Do not use a damaged tool or accessory.
  • Make sure the accessory is securely mounted to the tool.
  • Use the manufacturers’ recommended guarding for the accessory.
  • Wear personal protective equipment appropriate for the application.
  • Keep bystanders at a safe distance.
  • Never run the tool while carrying it at your side.
  • Make sure the accessory has come to a complete stop before putting the tool down.

If the accessory is not specifically recommended by the tool manufacturer, the following are some of the problems which can occur:

  • Accessories that are incorrectly sized cannot be properly guarded or the outside diameter and thickness of your accessory must be within the capacity rating of your power tool.
  • Accessories running faster than their rated speed can fly apart. The rated speed of the accessory must be at least equal to the maximum speed of the power tool.
  • Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may break or cause the operator to lose control.

Be safe - only use accessories recommended by the manufacturer of the power tool.
