Abrasive Cartridge Rolls – Straight & Tapered – Aluminium Oxide

When precision and finish matter, our Aluminium Oxide Abrasive Cartridge Rolls deliver. Designed for engineers, machinists and metalworkers, these rolls come in straight cylindrical or tapered (conical) shapes, in multiple sizes, to suit every finishing, blending, deburring or polishing demand in your workshop. Key Features Aluminium Oxide Coated Abrasive: Tough, versatile, good cut-rate on all common metals, long life, consistent performance. Two Shapes: Straight & Tapered Straight rolls are perfect for inside diameters, dead-end holes, lapping, finishing on cylindrical work. Tapered rolls can reach into channels, fillets, irregular concave contours, tight angles. When held at approx 45°, they get into corners; with reduced angle, they present more surface and cut faster. Range of Sizes & Grits/Grades: Coarse to fine (60 – 120grit). Large and small diameters, varied lengths to match mandrels or rotary tools. Multi-Layer Construction: Wound abrasive cloth; as outer layers wear, fresh grit is exposed. Good value and consistent cut throughout life. Cloth Backing Resin Bond: Durable cloth backing, securely bonded to aluminium oxide; gives toughness, flexibility and resistance to tearing or bursting. Mandrel compatible: Mount on Cartridge Roll Mandrels for use with rotary tools such as, die grinders, air tools, flexible shaft machines, pillar drills and micro motor systems etc. Safe, controllable, precise.

Speed & Efficiency: Faster stock removal when needed; fine finishing when required; tapered shape speeds work in corners. Cost-effective: Multi-layer design means you get more usable life per roll. Low cost per part/usage. Flexibility: One product line covers many applications: deburring, blending, polishing, removing tool marks, flash. Ease of use: Simple to mount; swapping grit or shape is easy. Reduced downtime. Applications Finishing inside diameters (bore, holes), dead-end holes, internal grooves. Deburring edges, removing flash from castings or welds. Blending or smoothing weld seams or joints. Polishing of small parts or components in precision engineering: tooling, moulds, fixtures. Machining & metalworking finishing steps: removing tool marks, fine surface prep. Work on high-tensile steels, stainless steel, aluminium, titanium (depending on grit), non-ferrous metals. Usage Tips & Best Practices Use appropriate grit: coarse (e.g. 60/80) for aggressive material removal or shaping and medium/fine (80/120) for blending Match the roll shape to geometry: use tapered rolls where you need to reach into concave or corner geometry; straight cylinders on flat or cylindrical inside surfaces. Mount securely on mandrel / arbor; ensure correct RPM per product spec to avoid overheating and excessive wear. Apply moderate, consistent pressure; avoid too much force, which wears out backing faster and may cause chatter. Replace rolls or flip to fresh layer when cut slows, to maintain finish quality. Use protective gear (eye protection, gloves); operate in well ventilated environment (dust control). Why Choose Our Rolls Over Others?

Support from precision engineering experts: help you pick the right roll for the job. Competitive pricing & consistent quality. We also offer Abrasive Jiffy Caps which are very similar to abrasive cartridge rolls, but provide a little more cut. ⇒ This product has multiple variants.

Tapered rolls are conical and allow access into corners, fillets, irregular concave contours. Using different angles also changes how much abrasive surface is engaged (e.g. flattening tapered roll increases cutting area). Which grit should I use for my application? Coarse grit (≈ 40-60): for stock removal, shaping and aggressive blending. Medium/Fine grit (≈ 80-120): for smoothing, blending tool marks, preparing for finish. What materials can I use these rolls on?Mostly metals: stainless steel, high-tensile steel, aluminium, brass, bronze, mild steel. Also possible on harder or softer metals depending on grit, and occasionally on non-metal materials where abrasive behaviour is suitable. Always test if unsure. What mandrel or tool is required?These rolls are designed to be used with mandrels or drive stems compatible with your drill, die grinder or micro-motor. Make sure the arbor or mandrel size matches the inner hole of the roll. Secure mounting is essential for safety and quality. – We offer compatible Abrasive Cartridge Mandrels here. How long will a roll last?It depends heavily on application: material, pressure, RPM, grit, and how hard the tool is used. But because of multi-layer cloth construction that reveals fresh abrasive, you get extended usable life compared with single-layer abrasives. How do I avoid damaging the workpiece or overheating?Use moderate pressure, keep tool speed appropriate, avoid staying in one spot too long. Use coolant or lubrication if required. Move roll constantly for more even abrasion.
