Siapupy Blind Hole Collet Bearing Puller Set 12pc 8–32mm with 360mm Slide Hammer, Hardened Steel Case

Siapupy 12-piece blind hole collet bearing puller set pairs eight expandable collets (8–32mm) with a 360mm slide hammer to extract bearings, bushings and sleeves from blind holes without extra tools.

This compact kit is built for internal and blind-hole removal tasks where conventional exterior pullers can't reach. Every component is made from heat-treated, precision-machined steel to resist wear and deliver a tight, non-slip grip inside bearing bores. The set ships in a molded plastic case so technicians can transport organized tooling to the garage, shop or job site.

How does the expandable collet system work for blind hole removal?

The collets expand inside the inner diameter of a bearing to create an inward-facing clamping action. Tightening the collet around the bearing wall gives a secure grip so the slide hammer can transfer pulling force straight out of the recess. This internal engagement reduces slippage and lowers the chance of damage to the bearing seating.

• Eight collet sizes cover 8–32mm bores for a wide range of bearings.
• Precision-machined teeth and taper ensure even expansion and hold.
• Internal pull method avoids contact with external flanges or housings.

What makes the slide hammer reliable for heavier pull jobs?

The included 360mm slide hammer gives controlled impact force to back out tightly seated parts. Heat-treated steel construction resists deformation under repeated hammering, so force is delivered where needed without bending components. The hammer length balances reach and leverage for most automotive and motorcycle applications.

• 360mm slide rod for deep or recessed bearings.
• Durable hardened steel absorbs repeated impacts.
• Threaded attachment points for secure collet-to-hammer connection.

Which tasks and vehicles is this puller set suited for?

This kit removes bearings, bushings and sleeves from blind holes in engines, gearboxes, hubs and housings. It works well for motorcycle wheel bearings, pilot bearings and smaller automotive hubs where an external grabber can't be used. Because the set covers multiple sizes, you can tackle varied jobs without frequent tool changes.

• Motorcycle and small vehicle wheel bearing removal.
• Pilot bearing and transmission bushing extraction.
• Service or repair tasks involving recessed bearings and sleeves.

How is the kit stored and protected for transport?

All parts come in a molded plastic case with dedicated compartments to keep the slide hammer and each collet secure. The case reduces the chance of lost parts and simplifies inventory before and after a job. Its lightweight design makes it convenient to carry between workstations.

• Molded case with individual slots for eight collets and hammer.
• Compact footprint fits standard toolboxes or vehicle trunks.
• Organized layout speeds selection of the correct collet size.

Who is this for: The Siapupy 12-piece blind hole collet bearing puller set is designed for professional mechanics, motorcycle technicians, and DIY enthusiasts who need a dependable internal puller for recessed bearings and sleeves. If you frequently service wheel bearings, pilot bearings or internal bushings and want a portable, complete kit with hardened steel parts, this set offers broad size coverage and a robust slide hammer for shop and field use.
