CAT40 TOOLS

QUICKFACTS

Measure your CAT40 or BT40 taper tools on your bench, quickly and reliably. This is the quickest, safest and most repeatable method for measuring CAT40 or BT40 tools.  We use this method ourselves, and supply our BT30 version of this tool with all our Tormach 1100MX and 770MXMX mill sales.  We've been requested by users to offer a CAT40 version, so here it is.  This tool measurement method is the same method we have all used for many years with TTS toolholder height measurement, but now adapted for CAT40 toolholders.

Simply zero your height gauge on the top reference surface, insert your toolholder, measure tool height offset, and enter the results in your tool table. Quick and easy! No more re-zeroing your ETS or spring gauge every time you re-start your mill! Measure tools at your bench or mount it on your mill for quick access.

• Hard anodized for durability
• Machined for CAT40 or BT40 7/24 taper and gage diameter.
• Three point taper contact for stable toolholder support
• Bottom surface tapped for 1/4-20 to allow mill or wall mounting

Note - CAT40 and BT40 toolholders index on shank taper diameter, not flange. TTS toolholders index on flange surface, not shank diameter.  Always measure all your tools by a consistent method.  Do not mix measurement methods, whether ETS, spring gauge, presetter, or touchoff.  Mixing measurement methods will yield different measurements and inconsistent Z height results.
