SGT SUPER GARAGE TOOLS 12pc Blind-Hole Bearing Puller Set — 8–32mm Collets, 14.2" Slide Hammer

SGT SUPER GARAGE TOOLS 12-piece Blind Hole Bearing Puller Set is a complete internal bearing extraction kit with a 14.2" slide hammer, two-jaw puller, and eight expandable collets sized 8–32 mm for safe, controlled removal of blind-hole bearings and bushings.

This professional-grade internal bearing puller kit is engineered to remove bearings, bushings, pilot bearings, and needle bearings from blind housings without needing access from behind the component. Built from heat-treated high-strength steel with corrosion-resistant finishes, the kit combines impact power and fine control so technicians and DIYers can extract tightly fitted internal parts while minimizing damage to hubs and housings. The tools stow neatly in a blow-molded case for transport and organized storage.

How does the kit remove bearings from blind holes?

The kit uses expandable collets inserted into the inner race of the bearing which are then expanded to grip the bore securely. A slide hammer imparts controlled impact force to pull the component free, while the two-jaw puller and threaded center bolts allow slower, tensioned extraction when the job calls for finesse.

• Choose the correct collet (8–32 mm) for the inner race diameter.
• Thread and expand the collet inside the bearing to lock the grip.
• Use the slide hammer for quick impact extraction or the two-jaw puller for controlled removal.

What sizes and parts are included, and which applications fit?

The set contains 12 pieces: a 360 mm (14.2") slide hammer, a two-jaw puller, two center bolts, and eight heat-treated expandable collets covering 8 mm to 32 mm. It works on car, motorcycle, bicycle, ATV, small engine, and light industrial blind-hole bearings and bushings when matched to the correct collet.

• Eight collets cover a broad range of inner diameters for most common bearings.
• Slide hammer length provides substantial stroke for tough extractions.
• Two center bolts and two-jaw puller offer alternatives for fragile or tight-fit components.

How durable and corrosion-resistant are the tools?

Components are forged from high-strength steel and the collets receive heat treatment to approximately HRC 30–35 for improved wear resistance and toughness. Protective finishes — a black corrosion-resistant coating and silver zinc plating on selected parts — extend life under workshop conditions.

• Heat-treated collets increase toughness and reduce deformation.
• Corrosion-resistant coatings limit rust during storage and use.
• Solid T-handle and robust slide-hammer construction resist bending during repeated impacts.

How do you use this kit safely to avoid hub or housing damage?

The kit is designed for controlled pulling: expandable collets create an even internal grip while the slide hammer and two-jaw puller apply steady, centered force. Proper setup, selecting the right collet, and using the slower two-jaw method for delicate parts reduce the risk of slipping or uneven pressure.

• Inspect the inner race and select the snug collet size before expansion.
• Center pull force and use controlled hammer strokes rather than excessive impact.
• Switch to the two-jaw and threaded bolt method for fragile or precision-fit components.

Who this is for: mechanics, motorcycle and bicycle technicians, small-engine and ATV repairers, and serious DIYers who frequently service blind-hole bearings and bushings. The kit suits users who need a portable, durable solution for internal bearing extraction that balances impact power with options for delicate removal. If you require a professional, organized toolset for removing a wide range of internal bearings without disassembling housings, this SGT SUPER GARAGE TOOLS set offers the parts and construction to get the job done reliably.
