An auto mechanic is unable to remove a broken exhaust stud from a Volvo engine head; standard extraction methods failed and the risk of damaging the aluminum head is high.

Existing tools (extractors, drill bits, welding) are ineffective when the bolt is broken deep in a recessed area and the parent material is soft aluminum; no guided extraction system exists for this scenario.

App Concept

BoltRescue Guide

A precision drilling and extraction guide system for automotive technicians. It uses a drill bushing jig that mounts over the broken stud, centers a carbide pilot drill, and steps up to a custom left-handed extractor. The aluminum head is protected by a heat-sink collar that prevents melting. It replaces guesswork and damage risk.

Key Features

Mountable drill guide with center-finding bushing for recessed broken bolts
Step-drill set optimized for hardened steel extractors
Left-handed extractor set with anti-slip flutes
Heat-sink collar to protect aluminum heads from welding/heat
Integrated chip evacuation channel to prevent bit breakage

Target Users: Automotive technicians and DIY mechanics who frequently deal with broken exhaust manifold studs on aluminum cylinder heads.

Revenue Model: $199 one-time kit purchase, with $29 refill packs for drill bits and extractors; $49/month subscription for online video library and customer support.
