Jlab Export is a leading Drilling Tool Manufacturer,and suppliers in India
Thrust and torque on a drill are the two loads this armed-wheel strain gauge dynamometer measures. The job is clamped in its work holder under the drilling machine spindle, and a two-channel digital indicator shows both readings during the cut. It takes holes up to 25 mm in mild steel.

Drilling Experiments for Students
The sensing unit is placed on the table of an Upright Drilling Machine, whose 25 mm drilling capacity matches it, or a Pillar Drill Machine. Students drill test holes with bits from an HSS Universal Drill Bit Set at several feeds and spindle speeds. They note thrust and torque for each hole.
Plotting the results shows how thrust and torque rise with feed and with drill diameter. From the torque and the spindle speed, students work out the power used at the drill. Holes drilled dry and with cutting fluid show what the fluid does to the torque.
Frequently Asked Questions
What size of hole can it handle?
It suits holes up to 25 mm in diameter in mild steel. Keep to that size so that thrust and torque stay within what the unit is built to read.
What does armed-wheel type mean?
The sensing element is a wheel with arms, like spokes, that carry strain gauges. Thrust from the drill bends the arms one way and torque bends them sideways, so the gauges can tell the two loads apart.
How is the dynamometer calibrated?
It is calibrated with a proving ring, so the indicator readings come out directly in kg. The balancing potentiometer sets the zero before each hole is drilled.
Why do thrust and torque rise with feed?
A larger feed makes each cutting lip take a thicker chip, so more metal is sheared in every turn. Both the axial push on the drill and the twisting load go up with it.
