Product Specification
1" KNOT WIRE END BRUSH - CARBON STEEL
When you need aggressive wire cleaning in recesses, openings, corners, and other hard-to-reach areas — but want more working coverage than a 3/4" end brush — the 1" Knot Wire End Brush - Carbon Steel is built for the job. Made with 0.020" carbon steel knotted wire, it delivers concentrated cleaning action for stubborn rust, scale, weld residue, oxidation, and surface buildup on compatible ferrous metals.
The knotted wire construction keeps the wire stiff under load, making it more aggressive than a flexible crimped end brush. Its end-on geometry directs the working tips into confined areas instead of spreading them across a broad surface, helping clean pockets, inside surfaces, holes, and fabricated details efficiently.
The larger 1" diameter provides more contact area than the 3/4" version while preserving the access advantage of an end brush. A 1/4" straight shank fits compatible chuck- and collet-equipped rotary tools, and the brush carries a 20,000 RPM maximum rating for properly matched equipment.

Features
-
1" end-brush profile provides more cleaning coverage than smaller end brushes
-
0.020" carbon steel knotted wire delivers stiff, aggressive cleaning action
- End-on geometry reaches into recesses, openings, corners, and inside surfaces
- More aggressive than flexible crimped-wire end brushes
-
1/4" straight shank for compatible chuck- and collet-equipped rotary tools
- 20,000 RPM maximum rating
- Excellent for localized rust, scale, oxidation, weld residue, and stubborn buildup
- Strong choice for fabrication, welding, maintenance, repair, and detail cleaning

Applications & Performance
Knotted end brushes are designed for aggressive localized cleaning in confined areas.
Common applications include:
- Cleaning recesses
- Inside-surface cleaning
- Cleaning holes and openings
- Corner and pocket cleanup
- Localized rust removal
- Scale removal
- Weld-area cleanup
- Oxidation removal
- Cleaning around fabricated details
- Removing stubborn deposits
- Maintenance and repair work
- Preparing difficult-to-access areas before coating or repair
The larger 1" diameter gives you more wire contact than a smaller end brush while still concentrating the working action forward into the area being cleaned.
Use controlled pressure and let the wire tips do the work.
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 end brush a convenient choice for cleaning and surface preparation with compatible corded and cordless drills. It mounts 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 drills may also be suitable when their chucks securely grip the 1/4" straight shank and their accessory instructions permit this 1" end brush. Keep the tool’s maximum speed within the brush’s 20,000 RPM rating, maintain working clearance, and follow the required shank-insertion instructions. Use rotary drill mode with hammer action switched off.
Safety Tips
- Never exceed the brush's 20,000 RPM maximum speed.
- Confirm the machine permits use of 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 controlled pressure. Excessive force can accelerate wire fatigue and brush 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.
