2-3/8" X 1/4" SHAFT MOUNTED CRIMPED CUP - CARBON STEEL
When you need more cleaning coverage than a small mounted cup but still want the control and accessibility of a 1/4" shank-mounted brush, the 2-3/8" x 1/4" Shaft Mounted Crimped Cup - Carbon Steel gives you a versatile middle ground. Its carbon steel crimped wire is designed for localized rust removal, oxidation cleanup, light deburring, surface deposits, and general maintenance on compatible ferrous metals.
The crimped cup construction allows the wire to flex as it contacts the workpiece, helping the brush conform to mild contours, edges, and irregular surfaces. Compared with the smaller 1-1/2" cup, the 2-3/8" diameter provides more working coverage per pass while remaining significantly more maneuverable than a full-size threaded angle-grinder cup.
A 1/4" straight shank fits compatible chuck- and collet-equipped rotary tools, and the brush carries a 13,000 RPM maximum rating. It is a practical choice for fabrication shops, maintenance departments, repair work, and general metal cleaning where you need controlled surface coverage without moving to a larger grinder-mounted brush.

Applications & Performance
This shaft-mounted crimped cup is designed for localized cleaning and light deburring with increased surface coverage.
Common applications include:
- Light rust removal
- Oxidation cleanup
- Surface contamination removal
- Light deburring
- Cleaning brackets and hardware
- Cleaning fabricated components
- Light weld-area cleanup
- Edge and corner cleaning
- Cleaning moderately contoured surfaces
- Preparing localized areas before coating or repair
- Maintenance and repair work
The larger 2-3/8" cup profile keeps more wire in contact with the workpiece than smaller shaft-mounted cups, helping you clean broader areas without giving up the control of a 1/4" shank-mounted accessory.
Use light to moderate pressure and let the wire tips do the cleaning.
Materials
Recommended for cleaning and surface preparation on compatible ferrous materials, including:
- Carbon steel
- Mild steel
- Structural steel
- Cast iron
- Wrought iron
- Other compatible ferrous metal surfaces
Keep carbon steel brushes dedicated to ferrous work when cross-contamination matters. For stainless-steel applications where iron contamination must be minimized, use a dedicated stainless steel wire brush.
Machine Compatibility
The 1/4" straight shank fits standard three-jaw drill chucks, making this brush a convenient choice for cleaning and surface preparation with compatible corded and cordless drills. It can be secured directly in suitable 3/8" and 1/2" drill chucks without a separate arbor adapter.
Compatible examples include:
-
DEWALT® DWD110 — corded drill with a 3/8" chuck.
-
Milwaukee® 0240-20 — corded drill with a 3/8" chuck.
-
Makita® HP1640 — corded hammer drill with a 1/2" chuck; use rotation-only mode.
-
Bosch® GSR12V-300 — cordless drill/driver with a 3/8" chuck.
-
RYOBI® PCL206 — cordless drill/driver with a 1/2" chuck.
Other machines may be compatible. Confirm secure shank engagement and clearance for the working brush. Other rotary drills or brush-approved collet tools may be suitable when their accessory instructions, capacity and speed match. Do not use hammer or impact action.
Safety Tips
- Never exceed the brush's 13,000 RPM maximum speed.
- Use only with a machine that permits this type and diameter of wire brush.
- Insert and securely clamp the 1/4" shank to the depth specified by the tool and brush manufacturers; keep unsupported shank extension within their limits.
- Use in rotary mode only; do not use with impact operation.
- Inspect the brush before every use and replace it if damaged, excessively worn, loose, or distorted.
- Maintain adequate clearance around the rotating brush and normal wire flare.
- Wear proper PPE, including eye and face protection, hearing protection, gloves, appropriate clothing, and respiratory protection when required.
- Keep bystanders away from the work area and direction of rotation.
- Use light to moderate pressure. Excessive force can flatten the crimped wire and accelerate wear.
- Allow the tool to reach operating speed before contacting the workpiece.
- Follow all operating and safety instructions for both the power tool and wire brush.
