Custom Cleaning Brush
Gun Bore Brush
Gun Bore Brush is built for bore, tube, and port where the brush must enter or follow internal walls, threads, and blind holes. Head size, working length, stem flexibility, and fill are selected to loosen chips, oil, and coolant without losing access or control.
Product Features
Radial bristles clean the complete bore circumference — The brush removes fouling, residue, and loose corrosion.
Fill matched to the barrel — Bronze, nylon, stainless, or other suitable filament can be selected.
Correct caliber sizing — Brush diameter is matched to the bore to maintain contact without excessive force.
Threaded stem fits cleaning rods — Standard or custom connections can be supplied.
Looped or protected core ends — End finishing reduces snagging.
Built to the cleaning system — Caliber, working length, filament, core, thread, and packaging can be customized.
Product Overview
Gun Bore Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts internal walls, threads, and blind holes to remove chips, oil, and coolant; the access path and minimum clearance determine whether the brush needs a rigid stem, a flexible extension, a tapered head, or a stepped cleaning section. Brush diameter, working length, tip form, and stem flexibility must match the complete passage.
Key dimensions start with Brush head diameter 2–20 mm, Brush head length 20–80 mm, and Handle length 50–150 mm. This configuration uses a tube-brush layout to reach inside bores, ports, and passages. The specified interface is threaded removable / fixed. Phosphor Bronze Wire, Nylon PA, and AISI 316 Stainless Steel Wire are the principal material directions in the current specification. The handle, neck, and head geometry should make the target easy to reach while keeping contact pressure manageable.

Application Areas
Gun Bore Brush is primarily mapped to Tube & Pipe Cleaning. Before applying the brush to another process, verify the surface, the route for removed debris, and the final finish target.
- Gun Bore Brush is best suited to firearm bore and chamber cleaning.
- The twisted-in-wire, flexible-rod, pull-through, fan-tip, or powered bore brush follows bore, chamber, rifling, forcing cone, and threaded cleaning-rod interface while the fill displaces powder fouling, carbon, metal deposits, oil, and loose residue.
- Use this configuration when the available access supports radial filament contact inside a bore, tube, hose, channel, nozzle, or drilled passage.
Selection Guidance
Structure fit
Match the tube & pipe bore brush geometry to internal walls, threads, and blind holes, the available access, and manual operation. Confirm Brush head diameter 2–20 mm, Brush head length 20–80 mm, and Handle length 50–150 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from Phosphor Bronze Wire, Nylon PA, and AISI 316 Stainless Steel Wire according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. The same material can feel very different depending on filament diameter, free trim, and fill density.
When to use another solution
For Gun Bore Brush, use another cleaning method when chips, oil, and coolant cannot be released by controlled filament contact, when internal walls, threads, and blind holes cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Gun Bore Brush be selected?
Start with firearm bore and chamber cleaning, bore, chamber, rifling, forcing cone, and threaded cleaning-rod interface, and powder fouling, carbon, metal deposits, oil, and loose residue. Then set Brush diameter, Working length, and Overall length, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Gun Bore Brush?
The primary dimensions are Brush diameter (2–20 mm), Working length (20–80 mm), and Overall length (50–150 mm). Also provide the minimum clearance, working envelope, trim or engagement, and the existing holder, shaft, stem, thread, or handle.
Which filament or contact material is used for Gun Bore Brush?
The primary options are Phosphor Bronze Wire, Nylon PA, and Stainless Steel Wire. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Gun Bore Brush not the best cleaning method?
Gun Bore Brush is not the first choice for pigs, flushing, ultrasonic, chemical descaling, blasting, or a flexible cable system for long, sharply curved, or heavily scaled passages.
What information is required to quote Gun Bore Brush?
Send the part or machine drawing, photos of bore, chamber, rifling, forcing cone, and threaded cleaning-rod interface, Brush diameter, Working length, Overall length, and Thread, the residue description, wet or dry conditions, motion or use method, temperature, preferred Phosphor Bronze Wire, Nylon PA, and Stainless Steel Wire, quantity, and the existing interface or sample.
