How Fast Should a Router Be Running?

If you've got a router with variable speed, then you've got the power to improve the quality of your cut. In general, the larger the bit, the slower the speed you need. The perfect solution for dealing with varying bit sizes is a variable speed router.

Here are general guidelines for most bits:

Hand Held Router Use

Bit size Bit size rpm
Small - 12.7 mm ⅙ to ½ 22,000+
12,7 mm - 28,6 mm ½ to 1 ⅛ 14,000 - 18,000
28.6 mm - 50,8 mm 1 ⅛ to 2" 12,000 - 14,000
