22pcs Metric Keyway Broach Set For Lathe
The DNYSYSJ 22-piece broach set provides a comprehensive range of metric keyways with B and C size broaches, along with collared bushings and gaskets. The kit includes B1, B4, B5, C6, C8 sizes and a selection of bushings (12B, 14B, 15B, 16B, 18C, 19C, 20C, 22C, 24C, 25C, 26C, 28C, 30C) and gaskets to support stable broaching on a lathe. Delivered in a neat box, the set aims for organized storage and accessible parts for quick changeovers during a project.
Why choose this kit for lathe work?
- Broad size coverage helps fit common keyways without fabricating new tools.
- Included slotted bushings and shims support precise alignment and consistent cuts.
- Compact storage reduces tool misplacement and improves workshop efficiency.
Accusize No 10-10A Combination H.S.S. Keyway Broach Sets
The Accusize 5100-0012 set offers essential HSS keyway broaches along with collared bushings and shims, packaged in a keepsake box. It includes several sizes in styles B and C, enabling users to widen or shape keyways with controlled accuracy. The inclusion of collared bushings helps prevent misalignment and reduces chatter during cutting, which is crucial for a clean finish on narrow slots.
Key considerations when selecting this kit:
- Range of broach sizes supports a variety of lathe applications, from small to mid-size keyways.
- Compact, varnished box makes storage and transport easy.
- Shims and bushings contribute to achieving repeatable results across multiple parts.
BANLICALI 18 Pcs HSS Keyway Broach Set With Wooden Case
This 18-piece BANLICALI set is built from high-speed steel with a grind finish for durability and edge retention. The kit emphasizes precision tooth geometry and a gradual cutter size progression, which helps minimize impact and extend tool life during broaching operations. The wooden case aids organization and protects the bits when not in use.
Useful buying notes:
- High-speed steel construction provides strong performance and longevity under typical lathe workloads
- Incremental cutter sizes reduce tool-induced stress and improve surface finish
- Compact storage case supports workspace organization
Carbide Tipped Wood Turning Tools Set (Aogbra)
While primarily marketed for wood turning, this carbide-tipped set demonstrates how indexable carbide edges can tolerate heavy use and maintain sharpness longer than standard HSS tools. The collection includes various cutter faces (Circle, Square, Diamond) and a Swan Neck Hollowing Tool, all designed to fit into a modular handle system. For lathe operators who work with mixed materials or wood-to-metal projects, these cutters offer notable versatility.
Key points for consideration:
- Carbide tips extend tool life, reducing downtime for sharpening
- Indexable inserts allow quick edge refresh without grinding
- Aluminum handles and protective case support portability and ergonomic handling
JMSMSH Lathe Centering Tool And Bump Roller
The JMSMSH Lathe Centering Tool is designed to help center and correct small workpieces that may not fit fully into a chuck. It supports alignment using a 1/2-inch square tool head and features a bump roller mechanism to quickly restore true stock alignment. This tool is particularly useful when preparing irregular pieces for broaching or when fine-tuning alignment prior to cutting.
Practical considerations include:
- Compact, lightweight design for easy maneuvering in tight lathe spaces
- Simple operation steps to achieve quick realignment
- Compatibility with common tool holders that accommodate 1/2″ square heads
Buying Guide: Key Purchase Considerations For Broaching On Lathes
Purpose and material compatibility
- Identify the material you will broach (steel, aluminum, brass, wood composites) and choose tools rated for that substrate. HSS and carbide tips offer different wear characteristics depending on the workpiece hardness.
- Consider whether you need straight keyways, tapered slots, or multiple standard sizes. Kits with a wide size range reduce the need for additional purchases later.
Tool design and durability
- HSS broaches with boxed storage and shims help achieve precise alignment and repeatable results.
- Carbide-tipped tools provide longer edge life for high-volume or demanding cycles but may come at a higher upfront cost.
- Indexable cutters offer quick edge refresh without retraining or resharpening, saving time on busy shop floors.
System compatibility and expansion
- Check whether the tool post, bushings, and collars fit your lathe’s spindle size and thread standards (for example, M14 x 2 on some tool posts).
- Look for sets that include storage cases and labeled bumpers or gaskets, which simplify inventory management and maintenance.
Maintenance, safety, and ergonomic factors
- Smooth operation depends on well-seated bushings and properly shimmed configurations to prevent chatter and tool misalignment.
- Ergonomics matter for frequent use; sets with comfortable handles and balanced weight reduce fatigue during long sessions.
- Inspect carbide tips and HSS edges regularly and rotate or replace worn edges promptly to maintain cut quality.
Value and total cost of ownership
- Factor in the total number of sizes included, storage options, and the potential for future tool upgrades or replacements.
- Consider whether a boxed kit saves time organizing parts versus purchasing individual pieces as needed.
