What Questions Have We Been Asked?
Is the T-Drill Pipe Cutter patented?
Yes, T-Drill Pipe Cutter is globally patented.
Why is the cutting result not exactly straight?
- The blade, or the diamond flange, is not sharp. During the cutting, the strong chipping forces bend the machine towards right.
- The gripper part has not been tightened sufficiently.
- The gripper part has not been cleaned, or lubricated. One or several of the guiding wheels are stuck, and therefore, not rotating.
- The outer surface of the pipe is dirty, or the pipe is not round.
- When cutting, the feeding speed is too fast.
- The blade, or the diamond flange, has not been tightened properly.
Can the blade be sharpened?
Yes, the TCT and Cermet blades can be sharpened 2-3 times. The sharpening can be performed in a professional sharpening machine shop.
Can you cut cast iron with a TCT or Cermet blade?
Yes, you can, but the blade will not last long.
Why was the diamond blade damaged already during the first cutting?
The feeding speed has been way too fast (the blade has been hit against the pipe to be cut).
Has the machine to be serviced?
Yes, and also the moving blade guard has to be checked for dust.
Other possible service matters have to be performed only by qualified service personnel.
How many times can I cut with one blade?
It is almost impossible to predict the durability of a certain type of a blade. How long the blade will last depends on, among other things:
- The material to be cut,
- The wall thickness of the pipe,
- The feeding speed while cutting,
- The feeding speed when starting the cutting; the blade meets the outer surface of the pipe.
Naturally, the user’s experience, and working habits influence also the durability of the blade.

Can the machine be fed reverse?
No, the cutting has to always be performed forward. Cutting reverse will damage the blade.
Can the machine circulate the pipe?
Yes, it is possible. However, in these types of cases, the supporting of the pipe has to be secured, and the possible tensions of the pipe have to be carefully taken into account.
Generally speaking, the T-Drill pipe cutting machines are not very suitable for the demolishing of existing, permanent pipe systems.
Is it possible to cut horizontally a pipe which is vertically located?
Yes, it is possible. If performing this task, two things are critical:
- The weight of the pipe above the cutting point has to be considered, and
- Supporting pieces have to be installed into the cutting gap. Otherwise, the blade will stuck towards the end of the cutting.
Have the T-Drill pipe cutting products been officially approved, and are they certified?
In the manufacturing, the following EU directives are followed: 98/37/EU and 98/336/EEC.
The machines fulfil the following standards:
- EC 50144-1 (2000)
- EC 50144-2-5
- EC 55014-2 (1997)
EC 61000-3-3 (1995) + Am.Al (2001)
