Create-Your-Own Workholders
Build a custom clamping system for holding lightweight objects such as beakers and laboratory equipment. First choose a base, and then add rods, connectors, and clamps.
Stainless steel components provide excellent corrosion resistance.
Rod-to-rod connector holds two rods at a 90° angle.
Clamps require a connector to attach to rods.

Swivel Bases for Kurt® Milling-Machine Vises
Screw Clamps
Use mounting bases to attach screw clamps to flat surfaces. Their threaded portion is machined at a slightly downward angle so the clamp can get a strong grip on the workpiece. Length is measured from under the screw collar.
Optional extra-large steel tips offer more gripping strength. Optional nonmarring plastic tips minimize damage to workpieces.
Revolving Screw Clamps
Mount the clamp in a threaded hole or on a mounting base (sold separately).
Jointed-Arm Magnetic-Base Indicator Holders
Position the arm by adjusting joints at the top, middle, and bottom. The magnetic base has a V-grooved bottom for mounting on curved and flat metal surfaces and a magnetic-release switch for easy setups. Holders have fine-adjustment knobs for precise positioning.

Flexible-Arm Magnetic-Base Indicator Holders
and Fine-Adjustment
Clamp
Adjust the flexible arm to nearly any position. These holders have a ball-and-socket segmented arm that locks in place with a lever. The magnetic base has a release switch for easy setups.
Holders with V-grooved base can be mounted on both curved and flat surfaces.
Holders with fine-adjustment base or clamp give you more precise control over positioning.
Clamp-On Indicator Holders
Attach the C-clamp on these holders to your milling machine head to take indicator measurements without obstructing the cutting tool. Use the fine-adjustment rod to precisely position the arm.
Overall reach is the distance from the center of the C-clamp to the end of the arm when both are extended.
Clamp-On Indicator Holders for Bridgeport J Heads
Attach the C-clamp on this holder to your Bridgeport J head to take indicator measurements without obstructing the cutting tool. Use the fine-adjustment rod to precisely position the arm.
Overall reach is the distance from the center of the C-clamp to the end of the arm when both are extended.
Flexible-Arm Clamp-On Indicator Holders
Vise-grip locking pliers clamp this holder to most thin, flat surfaces, and the flexible arm lets you position your indicator around obstructions. Lock the arm in place with a lever.
Economy Flexible-Arm Weighted-Base Indicator Holders
Adjust the flexible ball-and-socket segmented arm to nearly any position and lock in place. A heavy base adds stability.
Holders with a granite base have an extremely tight flatness tolerance. Their flatness gives you an accurate reference for inspection work and lets you move workpieces in and out smoothly. These holders have a fine-adjustment clamp to position indicators at precise angles.
Economy Jointed-Arm Weighted-Base Indicator Holders
Stabilize and precisely position your indicator with these weighted bases. Attached to the base, these holders have a jointed arm for moving your indicator up and down and in and out. Tighten the knob on the arm to lock it in place and use the fine-adjustment clamp for angling your indicator just right. Made of granite, the base has an extremely tight flatness tolerance, so it creates an accurate reference point for inspection work. It also means you can easily slide your workpiece in and out.

Economy Dial Plunger-Style Variance Indicators
with Jointed-Arm Magnetic-Base Holder
Jointed at the top, middle, and bottom, the arm holding these variance indicators adjusts to various angles. Turn the knob on the fine-adjustment clamp to angle them precisely. With a magnetic V-grooved base, they mount securely to both flat and curved metal surfaces. A spring-loaded plunger retracts and extends to measure objects. These indicators have a continuous dial numbered clockwise around the face, so it’s easy to see how much a dimension increases. Adjust the tolerance pointers to mark measurements that fall outside your limits. For quick dismounting, the base has a magnetic release switch.

Economy Electronic Plunger-Style Variance
Indicators with Rigid-Arm Magnetic-Base Holder
Stick the magnetic base onto metal surfaces for a secure hold while measuring. They have a V-grooved bottom that stays secure on flat and curved surfaces. To precisely position the indicator, adjust the knobs on the arm and clamp.
The indicator has a spring-loaded plunger that retracts and extends to measure objects. All have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off. A zero-set button lets you start measuring at any point.
All can send data to your computer using a USB cord (sold separately). To send data wirelessly, choose an indicator with either SPC data output or Bluetooth. Indicators with SPC data output transfer your measurement data to your device with the push of a button. You'll need a data transmitter/receiver set (sold separately). Indicators with Bluetooth send measurement data to your device wire-free and without an additional device.
IP67-rated indicators stand up to dust, coolant, and temporary submersion in water.
Tolerance checking indicators inform you when an item falls outside your set measurements.

Indicators with Jointed-Arm Magnetic-Base Holder
Adjust joints at the top, middle, and bottom of the base to position the indicator in place. Use the knob on the fine-adjustment clamp to precisely angle the indicator. The base is magnetic and has a V-groove on the bottom for a solid mount on flat and curved metal surfaces. Flip a switch to release the magnet.
A spring-loaded plunger extends and retracts from the indicator to take measurements. The measurements display on an easy-to-read LCD display. Start measuring at any point by pressing the zero-set button. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.
All can send data to your computer using a USB cord (sold separately). Indicators with Bluetooth Connection can transfer your measurement data wirelessly to your device with the push of a button. You'll need a data transmitter/receiver set (sold separately). .
IP67-rated indicators seal out coolant, water, and dust, so you can take measurements in dirty machining environments.
Tolerance checking indicators inform you when an item falls outside your set measurements.
