Yes, all the Big Foot 10-1/4” Blades have a diamond knockout. Just place your new Big Foot Blade so the writing is facing down and the hole is elevated up. Hit the corner of the round hole. The diamond knockout should pop right out.
No, it doesn’t wobble at all. The Big Foot 10-1/4” Blade was designed for the Big Foot Saw itself. The only reason for the Big Foot Blade to wobble is missing teeth or being dull. So always keep an extra 10-1/4” blade on hand with you.
The saw is an after- market attachment for your Skil/Bosch 7-1/4” saw. The 10-1/4” blade draws more amps than your factory saw. By using a 10-gage cord you will draw fewer amps, resulting in a longer life span for your Big Foot Saw. Twenty year-old Big Foot Saws are still in use today.
Unfortunately our Adapter Kit does NOT fit the Skilsaw 7-1/4″ Lightweight Magnesium saw (SPT77WML-22). The body of this saw is shorter that the regular 7-1/4″ skilsaw (SPT77W), however our parts are made of magnesium making the saw lighter than other 10-1/4″ saws.
