Boride Sanding and Smoothing Stones
Sanding and smoothing stones are perfect for removing small amounts of metal to get a final fit for your slide on the rails.
- Boride Rail Smoothing Stones: 6" x 0.5" x 0.115"
- Boride Sanding Jig Stones: 6" x 0.5" x 0.25"
Available in several grades from 120 grit to 800 grit.
Note: After using a Matrix Precision 1911/Sig Sauer Combo Rail Cutter, use a Boride Rail Smoothing Stone to smooth the inside of the rails. If the slide is fit too tightly, use a Boride Sanding Jig Stone in the Matrix Precision 1911 Sanding Jig to finalize the fit.
Be sure to use some light cutting oil or WD-40 so the stones don't clog up. We use CRC 3-36 as an oil and 400 grit to smooth out machine marks on our aluminum frames. It's the right grit to take off some material but not make noticeable scratches.
