Insert-Pro Shaper Cutter Accessories

Insert-Pro Shaper Cutter Accessories: Rub Collars and T-Bushings

Getting the most from any Insert-Pro shaper cutter requires the correct supporting hardware. Infinity Tools stocks the essential accessories that ensure safe cutter mounting, accurate depth control, and proper bearing surface for edge profiling: rub collars and T-bushings sized for the Insert-Pro platform.

Rub Collars for Edge Control

Rub collars ride against the workpiece edge or a starting pin to control cut depth without a fence. The Infinity Tools Rub Collars for Insert-Pro Shaper Cutters are machined to work with Insert-Pro cutter bodies, providing consistent depth of cut on curved or straight stock.

T-Bushings for 1-1/4" Bore Spindles

When your shaper runs a spindle smaller than the cutter's 1-1/4" bore, T-bushings reduce the bore to match. Infinity Tools offers both a 3-piece T-bushing set and a 2-piece T-bushing set for 1-1/4" bore shaper cutters, giving you options based on your machine's requirements. These accessories are used throughout the Insert-Pro line, including tools from the Insert-Pro Raised Panel Shaper Cutters and Insert-Pro Shaper Cutters for Cabinet Doors collections. If you have questions about which accessories your setup requires, the Infinity Tools contact page connects you with knowledgeable staff.

Frequently Asked Questions

What is a rub collar and how does it control cut depth on a shaper?

A rub collar is a smooth ring mounted above or below the cutter on the spindle. It contacts the workpiece edge or a starting pin to limit how far the cutter engages, setting the depth of cut without adjusting a fence. The Infinity Tools Rub Collars for Insert-Pro Shaper Cutters are designed for this purpose.

What is the difference between the 2-piece and 3-piece T-bushing sets?

The 3-piece T-bushing set provides more adapter combinations for varying spindle sizes, while the 2-piece set covers the most common single spindle-size reduction. Check your shaper's spindle diameter before selecting a set.

Do I always need a T-bushing with a 1-1/4" bore shaper cutter?

Only if your shaper's spindle is smaller than 1-1/4. If your spindle is already 1-1/4, no bushing is needed. For spindles of 1/2, 3/4, or 1, a T-bushing reduces the cutter bore to match.

Are these accessories compatible with all Insert-Pro cutter bodies?

Yes. The rub collars and T-bushings in this collection are designed for the Insert-Pro platform and are compatible with Insert-Pro cutter bodies across the door making, raised panel, and joinery collections.

Which Insert-Pro collections most commonly require these accessories?

Accessories from this collection are frequently used alongside tools from the Insert-Pro Raised Panel Shaper Cutters and Insert-Pro Shaper Cutters for Cabinet Doors collections.

Can rub collars be used on both straight and curved workpieces?

Yes. Rub collars are particularly valuable for curved or irregular workpieces where a fence cannot be used. The collar bears against the edge of the stock to maintain a consistent depth of cut throughout the pass.

Are T-bushings reusable across multiple shaper cutter bodies?

Yes. T-bushings can be moved between cutter bodies of the same bore size, so one set of bushings serves multiple Insert-Pro cutters in your shop as long as the bore size is consistent.

Does Infinity Tools offer price matching on accessories?

Yes. The price-match policy at Infinity Tools covers accessories as well as cutters. Review the full terms at infinitytools.com/pages/price-matching.

What is Infinity Tools' shipping policy on small accessory orders?

Shipping options and policies for all orders, including small accessory purchases, are described on the Infinity Tools shipping policies page.

How do I know which specific T-bushing or rub collar I need?

Refer to your shaper's spindle diameter and the bore size of your Insert-Pro cutter. If you are unsure, contact the Infinity Tools team through the contact page for guidance on the correct accessory for your setup.
