Overview
The Kreg 4-1/2-in. SureCut Fine Finishing 36-Tooth Saw Blade is a finishing blade sized for compact circular saws — the trim saws and one-handed cordless saws that get pulled out for tight cuts a full-size saw can't reach. Model number KSB45FF36. This is a fine-finishing tool: it's designed for plywood, hardwood, and trim work where the cut edge matters, not for demo or rough framing.
36 carbide-tipped teeth on a 4-1/2 in. plate is a dense grind for a saw this size, and that's the point. Compact circular saws are frequently used for exactly the kind of visible, close-quarters trim cuts where a rough edge is a problem — cutting door casing to fit, notching trim around an obstruction, or trimming plywood edge banding. A general-purpose compact blade tears through those cuts; this one leaves them clean.
The anti-stick coating and anti-vibration relief cuts matter proportionally more on a small blade than a large one. A compact saw is usually run one-handed and closer to the material, so any chatter or wander from vibration is more noticeable and harder to correct mid-cut. Keeping the plate coated and vibration-damped keeps a small, fast blade tracking straight in exactly those situations.
This blade fits a 3/8 in. arbor, which is the standard bore for 4-1/2 in. compact circular saws from most major brands — both corded and cordless.
Who should buy this: finish carpenters, cabinet installers, and DIYers who own a compact 4-1/2 in. circular saw and use it for trim, plywood, and hardwood work where the edge quality matters. If your compact saw is strictly a demo or rough-cutting tool, a general-purpose blade will serve you better and last longer under that kind of use.
Finish-Quality Cuts From a Compact Saw
36 carbide teeth on a 4-1/2 in. plate means your trim saw can leave the same clean edge as a full-size finishing blade, in the tight spots a full-size saw can't reach.
- 36-tooth carbide grind sized for compact circular saws
- Suited to plywood, hardwood, and trim cuts
Runs Clean in Close Quarters
Anti-stick coating keeps a small, hard-working blade from gumming up with pitch during repeated close-cut work.
- Anti-stick coating reduces friction and heat buildup
- Keeps the plate performing through repeated trim cuts
Steady in One-Handed Cuts
Compact saws are often run one-handed, which makes blade stability more noticeable. Relief cuts keep this plate tracking true.
- Anti-vibration relief cuts stabilize the blade at speed
- Helps hold a straight line in tight, close-quarters cuts

Pro Tip
Compact saws are easy to over-push because they feel so light in hand — ease off the feed rate on this blade and let the 36 teeth do the cutting; forcing it is the fastest way to bog down the motor and burn the edge.

Most compact-saw blades are an afterthought; this one is built to leave a real finish edge in the tight spots a big saw can't get into.
- Who it's for: Finish carpenters and DIYers running a 4-1/2 in. compact circular saw on trim and plywood.
- Why it stands out: 36 carbide teeth, anti-stick coating, and anti-vibration relief cuts on a size of blade that usually skips all three.
- Worth knowing: This is a finishing blade, not a demo blade — save it for cuts where the edge shows.
