Engineered for deep cleaning in narrow bores, ports, tubes, bearings, and cylinders, this twisted wire bore brush set delivers precise mechanical cleaning across a range of confined spaces. Available in brass, stainless steel, or a combined 10-piece set, each configuration includes 5 size variants spanning 6mm, 8mm, 10mm, 12mm, and 15mm to cover a broad range of bore diameters and tight clearance applications.

Twisted wire construction maintains brush integrity under repeated use, while the dual-material options allow selection based on surface sensitivity and cleaning intensity requirements. Brass brushes provide effective cleaning with reduced risk of surface scoring, while stainless steel brushes handle heavier deposits and more demanding industrial applications. Compatible with the included handle for manual use, or attachable to any power drill or die grinder for faster, more aggressive cleaning cycles. Available in 3 variants: 5-piece brass set, 5-piece stainless steel set, or 10-piece combined set.
