Jewelry Casting Cleanup Kit — Cratex Abrasive Wheels for Investment Cast Sprue Removal

From rough casting to pre-polish — without losing detail.

Casting is only half the battle. Getting from raw investment cast to a finished piece requires controlled material removal through a careful grit progression. Rush it and you'll reveal porosity. Use the wrong tool and you'll round over details you spent hours carving in wax.

This kit gives you both powered and hand options so you can match your tool to the situation.

What's Inside

• Cratex Mini Wheel Kit No. 107 — 12 mounted wheels across all 4 grits. For powered cleanup on broad cast surfaces: shanks, ring exteriors, pendant faces, and bracelet links.
• Cratex Mini Block Kit No. 128B — Flat blocks in all 4 grits for hand finishing. Maximum control on delicate cast pieces where a rotary tool would be too aggressive.
• 2 Extra Mandrels (1/8" shank) — Keep different grits loaded for seamless progression.

Perfect For

• Investment cast cleanup (gold, silver, bronze)
• Removing sprue attachment marks
• Smoothing parting lines from two-part molds
• Progressive finishing from medium through extra fine
• Delicate pieces where hand control matters more than speed

Why Jewelers Love This Kit

The rubber bond is forgiving on cast surfaces — it smooths without digging into porosity or tearing soft metals. Start with green (coarse) on heavy sprue marks, step through brown and red for general smoothing, and finish with white (extra fine) for pre-polish prep. The hand blocks let you slow down on precious castings where every tenth of a millimeter matters.

Includes: Cratex Mini Wheel Kit No. 107, Cratex Mini Block Kit No. 128B, 2 mandrels. Wheels on standard 1/8" shanks — flex shaft and rotary tool ready.
