Custom Cleaning Brush

Bore Brush

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

Full-circumference internal cleaning — Radial bristles contact the complete bore wall and remove residue from areas flat tools cannot reach.

Fill matched to routine bore maintenance — Nylon handles oil and loose dust, while brass or copper wire can address light oxidation on compatible bores.

Straight and flexible stem options — The brush can be rigid for aligned bores or semi-flexible for slightly curved passages.

Tip styles for through and blind holes — Cut, looped, fan, or capped ends can be chosen according to the bore termination.

Hand, drill, and machine connections — Threads, shanks, loops, and collet-compatible stems support different maintenance methods.

Made to the actual bore — Diameter, working length, filament, stem, tip, and interface can be matched to the drawing.

Product Overview

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 3.2–50.8 mm, Brush head length 25–127 mm, and Handle length 152–406 mm. This configuration uses a tube-brush layout to reach inside bores, ports, and passages. The specified interface is threaded removable / fixed. Brass Wire, Copper Wire, and Nylon PA are the principal material directions in the current specification. The brush should provide enough reach and control without making the user press the bristles too hard against the surface.

Application Areas

Bore Brush is primarily mapped to Tube & Pipe Cleaning. When adapting this brush to another job, confirm the workpiece surface, how debris will leave the area, and the required finish.

  • Bore Brush is best suited to tube, pipe, bore, hole, thread, cannula, housing, membrane, and internal-passage cleaning.
  • The twisted-in-wire, flexible-rod, pull-through, fan-tip, or powered bore brush follows internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity while the fill displaces scale, rust, chips, burrs, oil, coolant, deposits, powder, and biological 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 3.2–50.8 mm, Brush head length 25–127 mm, and Handle length 152–406 mm against the complete working envelope before finalizing the brush.

Contact material

Choose from Brass Wire, Copper Wire, and Nylon PA according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Do not choose stiffness from the material name alone. Filament size, free trim, and density control the final contact.

When to use another solution

For 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 Bore Brush be selected?

Start with tube, pipe, bore, hole, thread, cannula, housing, membrane, and internal-passage cleaning, internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity, and scale, rust, chips, burrs, oil, coolant, deposits, powder, and biological residue. Then set brush diameter, Brush section, and Overall length, choose the fill from the material and residue table, and match the mounting interface and operating condition.

Which dimensions define Bore Brush?

The primary dimensions are brush diameter (3.2–50.8 mm), Brush section (25–127 mm), and Overall length (152–406 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 Bore Brush?

The primary options are Brass Wire, Copper Wire, and Nylon PA. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.

When is Bore Brush not the best cleaning method?

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 Bore Brush?

Send the part or machine drawing, photos of internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity, brush diameter, Brush section, Overall length, and Filament diameter, the residue description, wet or dry conditions, motion or use method, temperature, preferred Brass Wire, Copper Wire, and Nylon PA, quantity, and the existing interface or sample.
