Geared Bench Drill TGH 25 / 400 V

The TGH 25 geared bench drill is a machine powered at 400 V, with a drilling capacity of up to 25 mm and tapping capacity up to M 10. Instead of a belt drive, it has a helical-tooth gearbox which, with the 0.65 / 1.2 kW two-speed motor, provides 8 speeds from 105 to 2,900 rpm. The drilling head rotates 360° and is height-adjustable on the Ø 100 mm ground steel column; rotation reversal for tapping and the automatic tool ejector are fitted as standard.

What are the main features of the TGH 25?

• Helical-tooth gearbox for optimum power transmission and quiet operation
• Two-speed motor with 8 speeds from 105 to 2,900 rpm
• Drilling head rotates 360° and is height-adjustable
• Clockwise/anticlockwise rotation reversal via selector switch, for tapping up to M 10
• Drilling capacity up to 25 mm with MT 3 Morse taper spindle mount
• Automatic tool ejector
• Precision ball bearings for high concentricity
• Ground steel column Ø 100 mm for high stability and load resistance
• Large 250 × 300 mm base with T-slots
• 120 mm quill stroke and height-adjustable guard

What applications is it suitable for?

The TGH 25 is suitable for machine shops, maintenance departments and metal fabrication shops that drill steel and other metals up to 25 mm and tap threads up to M 10. The minimum speed of 105 rpm with geared transmission ensures torque even at larger diameters, while the 360° rotating head makes it possible to reach workpieces positioned to the side of the base. It requires connection to a 400 V three-phase supply and a bench able to support approx. 130 kg.

It is not suitable for users with only a 230 V single-phase socket, nor for tapping above M 10: in these cases a 230 V model or a higher-capacity tapping drill is required.

What equipment is included with the TGH 25?

• Key-type geared chuck 3–16 mm / B 16 – for clamping drill bits from 3 to 16 mm.
• Arbor MT 3 / B 16 – to connect the chuck to the MT 3 Morse taper mount.
• Reducing sleeve MT 3 / MT 2 – for fitting tools with MT 2 Morse taper shanks.
• Automatic tool ejector – for quickly removing tools and chuck from the mount.
• Clockwise/anticlockwise reversing device – for reversing the direction of rotation during tapping.
• Height-adjustable guard – to protect the drilling area during machining.
