Tensilbits are the carbide cutting tools engineered specifically for the high speed specimen cutting achieved with the Tensilkut I and Tensilkut II. Super-sharp cutting edges combined with the proper angles of cut and relief are essential to achieve the fine shavings required for non-deformed specimen edges. The 40-74 Tensilbit is used specifically for general plastic cutting operations, and some customers have had excellent results using the 40-74 combined with very light passes to prepare specimens from hard materials such as stainless steel.
40-74 Tensilbit for plastics and hard materials
The 40-74 Tensilbit is an 8 flute, solid carbide cutter with a shank diameter of .500″. When used properly, Tensilbits can be resharpened, enabling you to extend their life.
40-74 Tensilbit: 8 flute, solid carbide
The 40-74 Tensilbit is designed for use with the 10-20 to 10-70 series Tensilkut I and all Tensilkut II models. They are in stock for immediate delivery. Please call for a price, or visit our website at www.tensilkut.com for more information on Tensilkut machines, Tensilbits and Tensilkut Master Templates.
Tensilbits are designed specifically for use with the Tensilkut I and Tensilkut II series machines. These carbide bits have a precise diameter with cutting edge angles, rakes and reliefs engineered for optimal surface finish on a variety of materials. Once a dulled cutting edge on a Tensilbit is noted, do not continue cutting your tensile specimens with that Tensilbit; permanent damage to the Tensilbit, including chipping of the edges can occur, making it impossible to resharpen the Tensilbits for extended use. A dulled edge will also result in a lesser quality surface finish, yielding inaccurate test results.
Before replacing the Tensilbit, be certain that you’ve used all available sections of your carbide Tensilbit by moving it up and down. This can be accomplished by loosening the bolt which holds the motor secure within its mount, and twisting the motor to move it up and down, allowing new sections of the carbide flutes on your Tensilbit to be used.
Tensilkut I
To install a new Tensilbit, remove the motor from its mound and loosen the collet with the wrenches provided with your Tensilkut machine. Remove the worn Tensilbit and insert the new one, sliding it far enough into the collet that it is securely held in place. Be certain that the chuck, chuck nut and Tensilbit are free of dirt and debris to insure trueness of the bit and accurate alighnment of the carbide cutting edges.
Tensilkut Master Templates
Tensilkut Engineering makes a wide variety of special templates to meet each customer’s needs. The ASTM A370 Template for making tensile samples with an 8″ gauge length is pictured at the top of this picture. Also shown is a template with bushings for drilling holes for use in pin loaded grips. Other custom configurations, including very small and very large templates, can be made.
Contact us for more information on completing your specimens.
This is the 50-36 Template. It was developed for people who need a narrower bar than the ASTM E8 standard, but want one longer than the standard subsized specimen.
50-36 Template
The 50-36 template makes a specimen which is .500″ overall width and about 8″ long. The gauge section is .250″ wide with a taper of .001″ to .002″, a gauge length of 2/00″, and a reduced length of 2.25″.
This template is used with the 10-33 table model Tensilkut I, 10-38 Floor model Tensilkut I, and the 10-85 Tensilkut II. Similar templates which make the same specimen are available for use with other Tensilkut models.

Tensilbits designed for use with the Tensilkut I and Tensilkut II series machines are essential to preparing your accurate test specimens. They are designed with specific angles, rakes and reliefs for accurate test sample preparation without distortion or tearing of the edges of your specimens. The 40-70 series Tensilbits are all .500″ diameter; all are designed for the best possible cutter life. If not chipped during use, Tensilbits can be resharpened for further use after they have become dull.

Every great invention, widely used or not, is born of someone’s need, and his or her ability to create a solution to that problem or need. The Tensilkut is one such invention. Created by a metallurgist working for a major corporation in 1954 when he encountered delays in getting his physical test specimens prepared by his company’s machine shop, the man soon patented his machine and struck out on his own.
The Tensilkut I is nearly identical to the machine created back in 1954. It is a precision milling machine designed specifically for machining flat tensile samples from metals and non metallics. Tensilkut machined specimens are free of induced heat or cold working distortion, and create test samples accurate to within +/-.0005″, when used with a Tensilkut template and cutter.
The test strip is clamped in a precision template which is manually moved across the Tensilkut table during the machining of the test specimen. The depth of cut is controlled by a micrometer control knob located on the control head. Specimens are cut in a series of light passes – the depth of each cut will depend upon both the material and its thickness. Of course, for the final passes, the recommended depth of cut is .0005″ to .001″. When the sample is machined to its final gauge width, the control head will reach a stop, and prevent further machining of the specimen. Additionally, the Tensilkut template assures repeatability of the specimens, so variations in test results will be caused by variations in the material.
In the past 50 years, tensile bars prepared on a Tensilkut machine have become the benchmark, as they have been proven to be the most rapid, economical and repeatably accurate samples a testing laboratory can use.
