I've been offered HSK 40 A and HSK 32A cartridges. I can't find any aftermarket HSK drawbars (new or used) of any kind though.

There's tons of new and used options for BT30, Cat 40 and R8 but I can't find a single listing for HSK ones on ebay, Amazon or any of the stores that sell auto drawbars for other tapers.

The only ones I've seen are as spare parts from VMC manufacturers (that offer an HSK option) but their prices are too high to be worth considering.

No point in getting a good deal on a spindle for a diy project if I'd have to spend thousands of dollars for the drawbar...
