Kolvoii CA-TK-014 54-Piece Bolt Extractor Kit with Left-Hand Bits
Product description
A rusted bolt or stripped screw can bring a repair to a standstill. The Kolvoii CA-TK-014 kit brings several extractor styles and left-hand drill bits together for removing damaged threaded fasteners. What helps when a fastener no longer has a usable drive? A selection of tools designed for extraction gives you more than one approach to the job.
Technical overview
The 54-piece set combines bolt and nut extractors, multi-spline extractors, left-hand cobalt drill bits and spiral screw extractors. Socket adapters in 1/4-inch and 3/8-inch sizes round out the selection, while the fitted case keeps the tools arranged for storage and access.
- Set: 54 pieces
- Materials: High-speed steel and chromium-molybdenum steel
- Finish: Black oxide
- Drill-bit cutting angle: 118 degrees

Rather than relying on a single extractor shape, this kit offers several styles for different fastener-removal tasks. That variety can be useful when working through a mixed repair box at home or on a vehicle, where damaged fasteners may call for different tools.
Everyday use
The set is intended for damaged, stripped, broken, rusted or rounded-off bolts and screws, as well as stuck studs and other threaded fasteners. A practical scenario is a repair where a bolt head has rounded and a standard driver can no longer get a secure hold: the extractor and drill-bit options provide tools selected for removal work, helping you tackle the fastener rather than replace the entire machine or assembly because of one damaged screw.
The case helps keep the components together between jobs and makes it easier to find the appropriate style when a repair calls for it. Buyers describe the set as versatile for different applications, though feedback on how effectively it works is mixed. Some also report that extractor bits can break during use, so choosing the appropriate extractor and working carefully matters for this kind of task.
Best use cases
This kit is suited to repair and maintenance tasks involving stubborn threaded fasteners in home, automotive or professional settings. The combination of bolt-and-nut, multi-spline and spiral extractors gives you options across common extraction jobs, while the left-hand drill bits provide another part of the removal setup. It is a useful format for a toolbox that needs more than one extractor type on hand, rather than a single-purpose tool for one specific fastener.
What does the kit include? It contains 17 bolt and nut extractors, 13 multi-spline extractors, 16 left-hand cobalt drill bits, 6 spiral screw extractors, and 1/4-inch and 3/8-inch socket adapters.
Before you decide
What fasteners is it designed to remove? The set is intended for damaged, stripped, broken, rusted and rounded-off bolts and screws, along with stuck studs and other threaded fasteners.
What materials are the tools made from? The listed materials are high-speed steel and chromium-molybdenum steel, with a black oxide finish.
How do buyers describe its performance? Feedback is mixed: some buyers find the tools useful across different jobs, while others report inconsistent extraction results and breakage. These are user experiences, not a guarantee of performance on a particular fastener.
Is it worth it?
For repairs that may involve more than one kind of damaged fastener, the CA-TK-014 brings multiple extractor styles and left-hand drill bits into one organized set. Its broad selection makes it a practical fit for keeping extraction tools ready for home, automotive and workshop maintenance.
