How much does the Dener TTH-12(C) cost?
Price estimate
We do not have a price for the Dener TTH-12(C) that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Of the five (C) columns in Dener's lathe tables, the TTH-12(C) shows the largest step down from its base model. The Dener TTH-12(C) lists a maximum turning diameter of 373 mm (14.7 in) and a machining length of 537 mm (21.1 in).
For the TTH-12 the same rows read 488 mm (19.2 in) and 614 mm (24.2 in). A 12 inch (305 mm) chuck in front of a 373 mm turning limit leaves little margin: the part cannot be much larger than the chuck that holds it. Anyone considering this column should lay out the largest part, with its jaws, against that figure before going further. Dener does not state what the (C) stands for.
The spindle data are those of the TTH-12. The bore is 118 mm (4.6 in), the bar capacity 95 mm (3.7 in), the speed 2,450 rpm, and the motor power is printed as 15/20.4 kW. So the model keeps the one thing the TTH-12 is bought for, the large through-hole, and gives up envelope around it.
Swing diameter is 650 mm (25.6 in). Rapid traverse is 30/30 m/min and cutting feed rate 1~10 m/min.
Pipe and bar work is least affected by the smaller envelope. Stock of 95 mm passes the spindle whatever the turning limit. Dener's option list includes a workpiece measuring system and a linear encoder for those who need closer control of size on such parts.

Strengths & Limitations
Strengths
- 118 mm (4.6 in) spindle bore and 95 mm (3.7 in) bar capacity, as on the TTH-12
- 12 inch (305 mm) chuck at 2,450 rpm
- Spindle motor power printed as 15/20.4 kW
- Workpiece measuring system and linear encoder are available as options
Limitations
- Turning diameter of 373 mm (14.7 in), far below the 488 mm (19.2 in) of the TTH-12
- Machining length of 537 mm (21.1 in)
- Little margin between chuck size and turning diameter
- The (C) designation is left unexplained
- Spindle speed of 2,450 rpm

Frequently Asked Questions
01
The TTH-12(C) lists a 373 mm (14.7 in) maximum turning diameter and a 537 mm (21.1 in) machining length. The TTH-12 lists 488 mm (19.2 in) and 614 mm (24.2 in). It is the largest gap between a (C) column and its base model in the range.
02
Yes. The spindle bore diameter is 118 mm (4.6 in) and the bar capacity 95 mm (3.7 in), identical to the base model, with a 12 inch (305 mm) chuck and a speed of 2,450 rpm.
03
First, what the (C) column represents, since the page does not say. Second, whether the largest part and its chuck jaws clear the 373 mm (14.7 in) turning diameter. Third, the tailstock, which is listed as a programmable option.
04
Rapid traverse is printed as 30/30 m/min for X/Z and the cutting feed rate as 1~10 m/min. Both rows are identical across the TTH models and their (C) columns.
