- Plywood
A 7-1/4 in. 40-tooth ATB finish blade for clean crosscuts, trim, and plywood. The thin 0.059 in. kerf helps cordless saws hold RPM, and the Perma-Shield coating resists pitch in softwood and PT lumber. It feeds slower than a 24T framing blade, isn't for ripping thick hardwood (gullets clog and burn), and can wander in a bound board.
Pros
- 40 ATB teeth leave a clean, near-splinter-free edge on trim and crosscuts
- Thin 0.059 in kerf reduces load so cordless saws hold RPM longer per charge
- Perma-Shield coating resists pitch buildup and gumming in softwoods and PT lumber
Cons
- 40 teeth cut noticeably slower than a 24T blade in thick framing stock
- Not intended for ripping thick hardwood; gullets clog and it can burn
- Thin kerf can wander if you push hard in a warped or bound board

Frequently Asked Questions
- What does a thin-kerf blade do for a cordless saw?
- It reduces the load on the motor, so a cordless saw holds RPM longer and gets more cuts per charge. At 0.059 in this is a genuinely thin kerf, which is why it pairs well with battery circular saws.
- Can you rip hardwood with this 40-tooth finish blade?
- It is not intended for it — the gullets clog and the blade can burn in thick hardwood. It is a crosscut and trim blade; ripping thick stock wants fewer teeth and deeper gullets.
- Does a thin kerf have a downside?
- Yes. A thin blade can wander if you push hard in a warped or bound board, so let the saw set the pace. The blade also cuts noticeably slower than a 24T in thick framing stock, which is the trade for the cleaner edge.
