Description

Haas compatible modular subplates

Tosa Tool builds OEM-fit modular fixture plates for Haas CNC mills and machining centers. These plates are designed around your machine’s table so you can mount once and change setups with modular workholding — without re-tramming a vise every job.

Machine series & models in the configurator

Use the dropdowns above to select series model → material. Current Haas options include:

VF Series: VF-1, VF-2, VF-3, VF-4, VF-5, VF-6
Mini Mills: MINI MILL, MINI MILL 2
Drill/Tap/Mills: DM-1, DM-2
Toolroom Mills: TM-0, TM-1, TM-2
Compact Mills: CM-1

If your Haas mill isn’t listed, we can still help — use the Custom Plate Builder or email your table size and model to dan@tosatool.com.

Add Options & built-to-fit accessories

Select your plate, then Add Options to your Modular Subplate and add built-to-fit hardware accessories. Available add-ons include:

Keyway locating bores & pins
Set screws and plugs
Plate mounting kit (t-nuts and capscrews)
TT 6″ modular vise
8″ modular angle plate
20-pc modular pin kit
Tosa Tool modular full kit or half kit (with shipping)

That way the plate and the accessories that fit it travel together in one order.

Tosa Tool hole pattern (TT)

The TT standard hole pattern is two nestled 1.2500″ grids sharing the same plate:

Precision bore grid: ø.5010″ ±.0002 TYP on 1.2500″ centers — for locating pins and accurate repeat setups
Threaded hole grid: 1/2-13 UNC 2B thru TYP on 1.2500″ centers, with ø.5625 × .19 counterbore (~3/16″ deep) — for clamps, bolts, and modular accessories

The two patterns are offset so bores and threaded holes alternate; neighboring holes (bore next to thread) fall on 0.625″ centers. Same pattern across Tosa Tool modular subplates so options and built-to-fit hardware accessories line up from plate to plate.

Material options

PH — 4140 PreHard steel: excellent strength and durability for production workholding
MC — medium-carbon steel: strong, long-life steel plate
AL — 7075-T6 aluminum: light but strong; popular when weight and handling matter

Made to order in Wisconsin

These plates are MTO from TosaTool LLC. Lead times are typically short for standard configurator builds confirm current timing when you order or ask Dan at 608-721-TOOL.

Complete the setup

After you select your plate, use Add Options to your Modular Subplate for built-to-fit hardware accessories — and check You May Also Like below for the modular vise, angle plates, and clamping kits that finish the TT-pattern setup.

Plate is great, ANGLE PLATE IS AWESOME, and the modular vise looks promising. We look forward to trying out more Tosa Tool hardware in the future. (get the setscrews and plugs right away). Took longer than expected, but our baseplate was a custom, – 1 star.

Awesome Plate! Love the delrin setscrews, WATERPROOF! No slime in my threads unlike other plates I own!

Hardware is great, but it took too long. Dan told us 2 months, we got delivery in 3 months. We like this hole pattern much more than others, it offers real modular rigidity (full bores for standard dowel pins) and more threads on the threaded holes.

I bought a oversize plate for our older Haas VF-4 and this has changed the pace of this shop immensely. Dan gave us a few pointers when we ordered and wow, has this changed our machining challenges.

We ordered on a Thursday, plate was halfway to us UPS by the next Tuesday. Amazing.
That was light speed.
Thank you!
Tosa Tool: Plate was a VF1AL, customer did pay a rush premium, and he also did pay extra for speedy delivery.
