Precision Quality Heavy Duty Lathe CNC Steel Bar Puller (25 mm x 25 mm – 1″ Shank)
- Shank Size: 25 mm x 25 mm Square
- Jaw Pull Range: 4 mm to 70 mm
- Brand: Turner Workholding
- Perk: Improves productivity on heavy-duty CNC bar pulling tasks
This puller excels for buyers who run mid-to-large bar diameters and require a robust, square 25 mm shank. Choose this if you regularly encounter multi-size jobs and need a dependable puller that can handle 4 mm to 70 mm jaw travel. Caution: Larger shank may require compatible tool turrets or mounting space on smaller lathes.
Precision Quality Heavy Duty Lathe CNC Steel Bar Puller (3/4″ Shank)
- Shank Size: 0.75″ Square
- Jaw Pull Range: 4 mm – 70 mm
- Brand: Turner Workholding
- Perk: Good balance of compact size and pulling force
Best for shops with limited spindle space but still needing a high-capacity puller for varied bar sizes. This option is better for smaller lathes than the 1″ versions while still delivering versatile jaw travel. Limitation: Slightly narrower shank reduces leverage on very large bars compared with 1″ models.
CNC Lathe Feeder Pull Clip, Shanrya Bar Puller (63mm / 16mm)
- One Piece Jaw Design reduces breakage risk
- Electroplated exterior for wear resistance
- Built-in non-slip screws to prevent jaw slippage
Selected for buyers prioritizing integrated jaw strength and reliable screw control. It is better for applications needing durable, simple pullers with built-in anti-slip features. Limitation: May have a shorter reach and may not suit very large bar diameters without adapters.
CNC Lathe Automatic Puller, 0.1-2in CNC Bar Puller for Machining
- Integrated Jaws for strength
- Hardened handle resists deformation
- Built-in non-slip screw and side lock screw to prevent loosening
Best for operators who need a versatile puller with adjustable jaw range from 0.1″ to 2″. Suitable for mixed-material workpieces and varying stock hardness. Limitation: Data notes on features are broad; verify jaw travel and compatibility with your turret / tailstock setup before use.
Turner Jumbo Heavy Duty CNC Lathe Bar Puller (1″ Shank, 55–118 mm)
- Shank: 25 mm x 25 mm Square (1″ Shank)
- Jaw Pull Range: 55 mm – 118 mm
- Brand: Turner Workholding
- Perk: Best for large-size jobs needing extended reach
Best for heavy-production environments handling larger bars, where reach and robust construction matter. Choose this if the job requires pulling longer stock with precise control. Limitation: Bulkier footprint may not fit small lathes or tight tool enclosures.
Buying Guide
What barrel size and shank matter most?
Shank size determines compatibility with your chuck, turret, or tailstock mounting. 25 mm x 25 mm and 1″ shanks offer strong leverage for mid-to-large diameter bars, while 0.75″ shanks suit tighter machines. Ensure the shank fits your machine’s tool interface and available mounting space.
How wide should the jaw travel be?
Jaw travel (or pull range) affects how much bar stock you can grip and extract in one pull. Wider ranges (e.g., 55 mm to 118 mm) enable larger bars and longer extraction distances, ideal for heavy-duty operations. Narrow ranges are sufficient for smaller diameters and quick setups.
What material and finish improve durability?
Look for hardened handles and electroplated or wear-resistant exteriors. Built-in non-slip screws help prevent jaw movement during pulling, reducing set-up errors and increasing repeatability on multiple parts.
Is it better to use a kit for gang-tool lathes?
For gang-tool configurations, a kit like the Dunham Tool Bar Puller Kit may provide multiple grippers sized from 3/16″ to 3/4″ that mount directly without adapters. This is useful for rapid changeovers and reducing downtime when handling varied bar sizes across tools.
Which puller is best for small CNC lathes?
Small-lathe users benefit from compact pullers with 1″ shanks or 3/4″ shanks and shorter jaw travel. These models fit tighter spaces while still delivering reliable bar extraction for lighter duty work.
Compatibility and installation tips
- Confirm mounting clearances around the spindle and tool turret before purchase.
- Check whether your lathe requires a square shank or a different interface.
- Inspect the puller’s jaw design; one-piece jaws reduce breakage risk in high-stress pulls.
FAQ
- What is a CNC bar puller used for?
A CNC bar puller is used to grip and extract bar stock from a CNC lathe, improving feed efficiency and reducing operator effort during part changes.
- What shank size should I choose for my lathe?
Choose a shank that matches your machine’s mounting interface. Common options include 25 mm x 25 mm, 1″ square, and 0.75″ shanks; ensure clearances with tool holders and chucks.
- Can a puller handle multiple bar diameters?
Yes, models with adjustable jaw travel or wider ranges can accommodate several stock sizes, typically from a few millimeters up to larger diameters.
- Are one-piece jaw designs more durable?
Single-piece jaws reduce the risk of joint failure and are generally more robust under repeated pulls than multi-piece designs.
- Is a kit better than a single puller?
A kit suits shops needing multiple gripper sizes or quick changeovers, especially on gang-tool lathes. A single puller may be more cost-effective for a focused, routine job.
- What maintenance is required for bar pullers?
Regularly check for jaw wear, ensure screws are tight, and clean any debris after use to preserve grip and longevity.
