Reywoo Blind Hole Collet Bearing Puller Set 8–32mm, 12pc Slide-Hammer Kit with Hardened Alloy Collets

The Reywoo Blind Hole Collet Bearing Puller Set is a 12-piece slide-hammer kit with eight expandable collets (8–32mm) designed to extract internal and pilot bearings from confined bores safely and precisely.

Engineered for mechanics, fabricators, and serious DIYers, this Reywoo kit combines a robust 12.5" slide hammer with a range of alloy-steel collets and pilots so you can remove internal bearings, sleeves, and bushings without cutting or damaging the housing. The components are hardened for longevity and finished to resist corrosion, offering dependable performance in garages and workshops.

How does this kit remove bearings from blind or recessed holes?

The set uses expandable collets that fit inside the bore and then expand to grip the inner surface of a bearing or sleeve. The slide hammer transmits impact force along the tool’s axis, pulling the part straight out of the housing without relying on external access points.

• Expandable collets cover 8–32mm diameters to match common pilot and inner bearing sizes.
• Slide-hammer action delivers controlled axial pulling force for stuck parts.
• Pilots and adapters center the collet for a secure, concentric grip.
• Alloy-steel construction reduces risk of deformation under load.

Which parts and jobs is the set best suited for?

This kit is intended for internal extractions where an external puller cannot engage the part—common tasks include removing pilot bearings, inner bushings, and small pressed-in sleeves. It works well in engine, transmission, gearbox, and small machinery service jobs where access is limited.

• Pilot bearing and clutch pilot removals in automotive work.
• Small internal bushings and sleeves in motorcycles and power equipment.
• Service and repair of transmissions, differentials, and housings.
• Any confined bore where traditional jaw or external pullers won’t fit.

How do you use the Reywoo slide hammer and collets safely and effectively?

Select the collet that most closely matches the inner diameter of the part, insert it fully, then expand it to lock against the inner surface. Attach the slide-hammer assembly, apply steady pulls until the part dislodges, and use controlled impacts to avoid sudden releases that could damage surrounding components.

• Choose the correct collet size and test-fit before expansion.
• Expand the collet evenly to ensure a concentric grip on the part.
• Use firm, controlled strikes on the slide hammer—avoid excessive force.
• Wear safety glasses and secure the workpiece to prevent movement.

What materials and maintenance will keep the tools reliable?

The Reywoo components are made from hardened alloy steel and finished to resist wear and surface corrosion for long service life. Routine cleaning and light lubrication of threads and the hammer shaft will prevent rust and keep moving parts operating smoothly.

• Wipe components clean after each use to remove grease and debris.
• Apply light oil to the slide hammer shaft and threads periodically.
• Inspect collet edges for deformation before reuse; replace if damaged.
• Store the kit in a dry case to prevent moisture exposure.

Who is this for: The Reywoo Blind Hole Collet Bearing Puller Set suits professional technicians, restoration specialists, and knowledgeable DIY mechanics who need a compact, reliable solution for extracting internal bearings and sleeves from tight bores. If you frequently service engines, gearboxes, or small machinery and require a non-destructive, repeatable extraction method, this kit delivers the size range, strength, and workflow to get the job done.
