BGS 70968 Review

There are few things more frustrating than being stuck at the roadside with a flat tyre, only to discover that the wheel is rusted solid to the hub and refuses to budge. No amount of kicking, pulling, or levering will shift it — and if it does come loose, the mating surface underneath is often pitted with corrosion that prevents the new wheel from seating properly. This is a common problem for anyone who lives in a region with wet winters, road salt, or coastal air. Professional mechanics deal with seized wheels every day, and they know that proper hub preparation is not optional — it is essential for safety, for accurate torque settings, and for making sure the next tyre change goes smoothly. The right tool turns a tedious, time-consuming job of scraping and wire-brushing into a quick, clean operation that leaves the hub surface flat, rust-free, and ready to accept the wheel.

Wheel hub cleaning tools are a relatively niche category in the automotive world, but for anyone who changes wheels regularly — whether in a professional workshop, a tyre shop, or a home garage — they are a genuine time-saver. The basic idea is simple: a disc-shaped abrasive surface that spins against the wheel hub and brake disc mounting face, stripping away rust, brake dust, and road grime in seconds. What matters is how well the tool fits modern vehicles, how easy it is to drive with common workshop tools, and whether the abrasive discs last through multiple uses. BGS is a German tool brand that specialises in professional automotive workshop equipment, and their tools are designed with the realities of daily garage use in mind — they need to work reliably, hold up under repeated use, and not cost a fortune to keep supplied with consumables.

In this review, we examine what makes this particular hub cleaning tool worth considering. We look at the design and build quality, how it performs on different vehicle types, what tools you need to drive it, the availability and cost of replacement discs, and whether the price represents good value for a professional or serious DIY user. We also draw on feedback from over 200 verified purchasers to understand how it holds up in real workshop conditions.

The BGS 70968 is a purpose-built wheel hub and brake disc cleaning tool with a 150 mm overall diameter and a 90 mm inner cutout, specifically optimised for modern vehicles that have larger hub centring rings. The body is made from durable plastic with a bonded silicon carbide abrasive surface that is coarse enough to strip rust quickly without being so aggressive that it gouges the metal underneath. It mounts via a 12.5 mm (1/2 inch) female square drive, which means it fits directly onto the anvil of any standard impact wrench or cordless screwdriver — no adaptors needed. The manufacturer specifies a maximum rotational speed of 1,200 revolutions per minute, which is well within the range of most cordless impact drivers and mid-range impact wrenches. The hook-and-loop (Velcro-style) backing allows for quick replacement of the abrasive disc without tools, and replacement discs are available separately under part number 70968-1.

The design of the 70968 addresses two practical problems that earlier hub cleaning tools often missed. First, the 90 mm inner diameter is deliberately larger than older designs, which means it clears the raised hub centring ring found on most vehicles built in the last two decades. Second, the plastic body is lighter and less likely to damage alloy wheels or brake components if it glances against them during use — steel-bodied alternatives can leave dents and scratches if your hand slips. The sanding surface has a slight bell shape, which helps it conform to the slightly domed profile of many hub faces and brake disc mounting surfaces, ensuring even contact and consistent cleaning across the whole area.

Using this tool is straightforward. Mount it onto an impact wrench or cordless driver with a 1/2 inch square drive, position it against the hub face, and pull the trigger. The abrasive disc removes surface rust, brake dust deposits, and old anti-seize compound in seconds. Because the tool is driven by a powered wrench rather than by hand, there is none of the repetitive scrubbing that makes manual wire-brushing so tedious. The 150 mm diameter covers the full hub face of most passenger cars, vans, and large saloons in a single pass. For best results, keep the tool flat against the hub and let the abrasive do the work — pressing too hard will wear the disc faster without speeding up the cleaning significantly. A light coat of anti-seize or copper grease after cleaning is still recommended to prevent future corrosion.

In the box, you receive the wheel hub grinder body with the abrasive disc pre-attached. No additional accessories are included, and the tool does not come with a storage case. Replacement abrasive discs are available from BGS under part number 70968-1, and they are reasonably priced, so the ongoing running costs are low. The hook-and-loop fastening system makes disc changes quick — peel off the old one and press on the new one, no tools or alignment needed. It is worth noting that this tool is designed specifically for use with impact wrenches and cordless screwdrivers with a 1/2 inch square drive. It will not work with standard drill chucks, angle grinders, or rotary tools, so make sure you have a compatible driver before purchasing.

The tool's compact dimensions of approximately 150 × 150 mm and lightweight plastic construction make it easy to store in a toolbox drawer or hang on a pegboard. On Amazon, it holds an excellent rating of 4.6 out of 5 stars from 224 verified purchasers, making it one of the highest-rated products in the wheel bearing tools category, where it ranks at number 106 in Wheel Bearing Tools. At a price of roughly €45.20, it represents good value for a professional-grade workshop tool that pays for itself in saved time after just a handful of wheel changes. The positive customer feedback consistently highlights how much faster hub cleaning becomes compared to manual methods, and many reviewers note that it has become an indispensable part of their tyre change routine.

A must-have time-saving tool for professional mechanics and tyre shop technicians who need to clean wheel hubs and brake disc mounting surfaces quickly before fitting wheels, as well as dedicated home mechanics who do seasonal tyre changes.
