The set combines eight expandable collets, a robust slide hammer, and fittings organized in a portable case so you can reach recessed parts without machining or complex fixtures. Built of hardened carbon steel and stored in a molded carry box, the kit aims to balance strength, versatility and portability for DIYers and professional mechanics alike.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the collet system grip internal bearings securely?\u003c\/h3\u003e\n\u003cp\u003eThe collets expand inside the bore and lock against the inner surface of the bearing or race, transferring pulling force from the slide hammer to the part. Proper collet selection and full expansion ensure a concentric grip that minimizes slippage and damage. The mechanism avoids external claws on delicate housings, making it ideal for blind-hole extractions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEight expandable collet sizes covering 8–32 mm inner diameters\u003c\/li\u003e\n  \u003cli\u003eConical wedge action for radial expansion and firm hold\u003c\/li\u003e\n  \u003cli\u003eDesigned for concentric gripping to reduce component marring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat kinds of jobs and vehicles can this tool handle?\u003c\/h3\u003e\n\u003cp\u003eThis extractor is suited for internal bearing and bushing removals in motorcycles, scooters, compact cars, ATVs and many light automotive or industrial assemblies. It performs best on recessed parts where external pullers cannot engage. For larger heavy-duty bearings, a bigger professional system may be preferable.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCommonly used on motorcycle wheel bearings, hub inner races and small gearbox bearings\u003c\/li\u003e\n  \u003cli\u003eWorks with compact car and ATV internal bearings within the 8–32 mm range\u003c\/li\u003e\n  \u003cli\u003eUseful for engine or transmission housings with blind bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do you set up and operate the slide hammer assembly?\u003c\/h3\u003e\n\u003cp\u003eChoose a collet that matches the internal diameter, insert it into the bearing bore and drive or pull the collet so the wedge expands. Attach the slide hammer to the collet fitting and deliver measured impacts to extract the part.

If you need a portable, reusable method to remove blind-hole internal parts between 8 and 32 mm without destructive cutting or welding, this kit provides a practical, mid-range solution. For frequent heavy industrial extractions beyond the specified size range, consider a larger commercial-grade system.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What inner bearing sizes does this kit cover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The kit covers internal diameters from 8 mm up to 32 mm using eight expandable collets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the slide hammer length suitable for tight spaces?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
