Tormach Mill Tool Table

Tormach Mill Tool Table

Tool numbers, lengths, and diameters for the Tormach metal CNC mill, copied from a PathPilot tool-table export.

PathPilot uses this list when a program calls a tool (T1 M6, and so on). The Z offset is the tool length in inches, so the Z zero on the part stays put after a tool change. The diameter is the cutter width in inches. Conversational programming and cutter compensation both use it.

This is a copy of that file. It is not a live reading of the machine. If a cutter has been swapped, touched off again, or removed since 9 October 2026, trust the tool in the holder and the table on the controller, then update this page.

What the numbers mean

Tool number is the number PathPilot and G-code use for that cutter.
Description is the name stored in PathPilot. Shorthand is listed under the table.
Z offset is the tool length in inches. A larger number is a longer tool. 0 means the length was never set. Running that tool against a part Z zero will not cut where the program expects.
Diameter is the cutter diameter in inches. 0 means the diameter was never set.

Values below are inches, as stored in the export, rounded to four decimal places.

Tools

Tool	PathPilot description	Z offset (in)	Diameter (in)	Notes
1	flat 2FL R0 loc1.5 HSS dia:0.500 loc:1.500	3.3370	0.5000	1/2“ 2-flute flat HSS, 1.5” length of cut
2	endmill 2fl loc:1.000 hss	3.3360	0.4970	Stored diameter is 0.497“, not 0.500”
3	flat 4FL R0 loc:1.920 HSS	4.0070	0.4640	Description does not name a size. Stored diameter is 0.464“
4	flat 2fl r0 loc:1.100 hss	0.9370	0.2580	Z offset is much shorter than the other end mills. Confirm the touch-off before use
5	6 fl hss chamfer	2.7355	0.4000	Chamfer mill
6	2 fl hss flat	2.7255	0.2600	Description does not name a size. Stored diameter is 0.260”
7	flat mill 2fl carb	3.6860	0.4750	Carbide. Description does not name a size
8	FacingTool	0	3.7500	Length is not set
11	2f endmill	1.0000	0.0020	Diameter of 0.002“ and a Z offset of exactly 1. Treat this as leftover test data until someone measures a real cutter
19	1/8” 2fl flat mill hss	0.3150	0.1230	Stored diameter is 0.123031“ (3.125 mm), short of a true 1/8” (0.125“)
20	Edge Finder	3.6880	0.2000
21	3/8 flat End Mill	0	0.1875	Name says 3/8” (0.375“). Stored diameter is 3/16” (0.1875“). Length is not set
22	3/16 Ball End Mill	0	0.1875	Diameter matches the 3/16” name. Length is not set
98	Haimer	0	0	Length and diameter are not set
99	Tormach Pasive Probe	0	0	Spelled that way in PathPilot. Length and diameter are not set

Slots 9, 10, 12–18, and 100–107 are empty in the export (no description, length 0, diameter 0).

Description shorthand

fl / FL — number of flutes
R0 / r0 — square end (corner radius 0)
loc — length of cut
HSS — high speed steel
carb — carbide
dia — diameter

Holder notes on tools 12 and 13

These two notes were typed into an extra spreadsheet column. PathPilot does not have a tool-holder column, and both descriptions are still blank. Both notes end in a question mark, so confirm them at the machine:

Tool 12 — “TTS-ER20??” (Tormach Tooling System holder, ER20 collet chuck)
Tool 13 — “TTS-JT6 with 5/8” Drill Chuck?“ (TTS holder with a Jacobs taper drill chuck)

Putting this file back into PathPilot

The first row of the export has to stay the first row, and its first three cells have to stay as exported:

Mill Tool Table
the original timestamp and v1
This must be the first row - do not edit

The “Tool Holder” label and the notes on tools 12 and 13 sit outside those columns. They are spreadsheet notes. They are not controller data.
