Insert-Pro Rail & Stile for Interior & Exterior Doors

Our Insert-Pro Shaper System offers the very best in quality and versatility for your shaping needs. Precision machined from durable aircraft-grade aluminum, the tool bodies feature a tough anodized finish for years of service in your shop. We use only the highest quality C4 micro-grain carbide for the replaceable cutting knives, and precision grind each one to a mirror finish and razor sharp edge.

Our exclusive new door making system accepts five popular profiles for making custom interior and exterior doors. Simply re-stack the cutters to make both the rail and stile cuts as shown in the illustration. These sets make 1-3/8" thick doors. For thicker Exterior Doors (1-3/4") make sure to add our optional Exterior Door Making Kit (item 84-058).

Each cutter head has a 1-1/4" bore and a diameter of 4-3/4" and produce a 5/8" wide tenon. To produce doors with tenons up to 2" wide, see our exclusive Extended Tenon Cutter Heads.

Follow this link for replacement insert knives or for additional door profiles. They're also useful for setting your fence for straight stock. Want to make arched top doors? Pick up a 3-1/2" diameter Infinity Tools Rub Collar (RUB-105) here. Don't have a 1-1/4" Spindle? We offer a line of T-Bushings to fit Infinity Tools Shaper Cutters on 3/4", 1/2", and 30mm Spindles.

Look under the Documents tab above to download the instructions for setting up the rail and stile cut for interior and exterior doors.

William G. ★★★★★

The aircraft-grade machining on these shaper cutters is immediately obvious—they spin up perfectly balanced on my shaper. I used them for a set of custom interior doors and the rail and stile joints came out glass-smooth with zero tear-out. Absolutely worth it for the precision.

David ★★★★★

I was a little nervous about the precision on the stile profiles, but the machined fit of these interchangeable cutters is spot on—zero chatter even on hard maple. The 1-1/4" bore seated perfectly on my shaper, and the door joints came together tighter than anything I’ve gotten from a stacked router

Timothy ★★★★★

The cutters are rock solid in the holder, zero wobble even on a full-depth pass through oak. I’ve made three interior doors this week and the rail and stile profiles come out crisp with no tear-out.
