  • Good product
Style: 1 Pack Pattern Name: Up Cut Size: 1/4”Dia x 2”CL x 4”OAL

  • They stay very sharp
Love these bits, keep spares in stock just in case I break one.

  • Alright for the price
Style: 1 Pack Pattern Name: Up Cut Size: 1/4”Dia x 2”CL x 4”OAL
For the price this bit will get the job done. It doesn't cut the cleanest so I question how sharp it is, but a little sanding has my parts up to scratch. If you want a clean finish straight off the machine you'll have to pay $15-50 more depending where you shop but for me this just hit that good enough line. ... show more

  • Extra long bit
Style: 1 Pack Pattern Name: Up Cut Size: 1/4”Dia x 2”CL x 4”OAL
This bit worked very well for cutting fairly deep half lap joints. It’s arguably not the finest bit on the market but it’s 2” length overshadows any other disadvantages the bit may have.
