Spring in Tennessee

April 12, 2018

Spring actually arrived a couple of weeks ago in Tennessee, but we take pride in keeping the Tensilkut building looking inviting.

Tensilsaw Demo

July 28, 2017

The Tensilsaw, with the 60-66 diamond plated Tensilsaw Blade, is perfect for cutting fiber filled plaques into strips, as shown in this video.

The Tensilsaw cuts through this sheet very efficiently, creating strips which are ready to be cut into tensile bars on the Tensilkut I, Tensilkut II or CNC Tensilkut III, notched for izod impact testing in accordance with ASTM D256, or used for flexural or other tests requiring a straight strip of a precise width.  The width is controlled via precision spacers, ensuring that the width doesn’t change unless you wish to change it.


For more information on the Tensilsaw or ways to make your testing program more efficient, please visit our website at or fill out the contact form below.

Demonstration of the Tensilkut II

June 23, 2015

The Tensilkut II is used to easily prepare flat tensile, compression, flexural and other specimens from metals and non-metallics.  This machine is designed for operation in the testing lab by technicians without previous machining experience.

The starting blank is inserted into the Tensilkut Master Template, and the clamping screws are tightened as shown in this video.  The micrometer dial on the Tensilkut control head is set to its starting position, and a series of light passes are taken to cut the material from each side of the specimen.  When the correct tensile specimen dimensions are achieved, the micrometer dial will stop turning, thus preventing cutting an undersized test specimen.  After removing the completed ASTM E8 or other specimen from the master template, the tensile bar is ready for immediate testing.

The Tensilshear is an easy way to cut strips from small sheets of metal, including aluminum, brass, steel, and even harder materials.

A pair of micrometer adjustments on the back move the stop to enable you to simply push your sheet of up to 10″ wide metal under the blade until it reaches the stop, make sure it’s firmly in place, and cut off a strip.  The process can be repeated for as many strips as you need. It is a compact, manually operated unit, requiring neither electrical nor air hookup to operate.

The Tensilshear will shear strips from 1/8″ (3mm) thick aluminum or materials of similar hardness, and up to 2mm thick steel.  The hardened, precision ground blades are adjustable to eliminate virtually all edge burring problems.  The video below shows the Tensilshear being used to shear strips from 2mm thick hardened steel.

Tensilbits for Cutting Kevlar

May 2, 2015

Cutting Kevlar and similar non-woven fabrics into tensile test bars is tricky.  Conventional cutting methods yield irregular edges and/or fraying at the edge.

To cut a tensile test specimen from Kevlar using the Tensilkut machine, start with the 40-75 Tensilbit.  Following the standard procedure for using the Tensilkut, make progressive passes along each side until the specimen is .005″ oversized.

Switch to the 40-76 Tensilbit, and finish the specimen.  The diamond coating on the 40-76 will smooth the finish and remove the frayed edges, ensuring an excellent tensile specimen from Kevlar.

Tensilkut also manufactures the “Bow Tie Tensile Specimen” Master template.  This specification was developed specifically for testing Kevlar.

The 40-75 Tensilbit is our solid carbide, burr type Tensilbit, which has long been used in preparation of glass laminates, composites and fiberglass specimens.  The burr ensures that the fibers in Kevlar, fiberglass and other composites will be evenly cut, resulting in non-deformed edges and a good surface finish.

The 40-76 Tensilbit is a .500″ diameter tool steel shank with a diamond coating which removes material with a sanding action.  It is an excellent choice for materials which have a tendency to crack when cut, such as certain ceramics, or for finishing edges on composite or glass filled materials.

Bothe the 40-75 Tensilbit and 40-76 Tensilbit are designed for use with the 10-20 through 10-70 series Tensilkut I, and all Tensilkut II models.  Visit our website at for more information on preparing test specimens on the Tensilkut machine.
