Sherline ER25 Spindle Upgraded Headstock
Quick Note! - Because of High Demand for the ER25 - We are now accepting new orders for the next shipment. On average, it's taking about 3 months to get our parts orders in (we keep selling out and the supply chain is still slow). To keep things fair, we can only hold "spots" in the next order for paid customers. In other words, the longer a person waits to order, the more likely they will miss out on getting in on the current order batch. This is because, just like the previous order, the incoming order will likely sell out before we even get it! Thanks, James...
ER-25 Precision Instrument - Sherline Converted Headstock
For: Lathe, Mills or custom project
If you are looking for the Sherline ER collet conversion that works best for super high speeds, this is the one. The ER-25 has less moving mass and works well with very high speeds. Plus, you can finally get the high level of precision you want out of a Sherline (without using tiny 1160 & 1162 WW Sherline collets). Let's face it, to holding larger stock with the Sherline jaw chucks gives limited precision and camping surface area. This problem is now solved with you new headstock.
- ER25 Collet sizes ranges available 1/16” to 5/8”
- Through hole is .30”(optional .55” Large Bore for larger long stock)
- .0005" or runout at the collet mating surface
- Optional ABEC-7 Angular Contact Bearings (Sherline stock bearings aren't really high precision)
- Optional .55" ID Large Bore
>>>IMPORTANT NOTE: IF YOU REQUIRE ABSOLUTE PRECISION, I HIGHLY RECOMMEND THAT OUT INVEST IN THE ADJUSTABLE ER COLLET NUT...YOU CAN DIAL IN YOUR PART TO ALMOST ZERO MEASUREABLE RUNOUT (IF YOUR PART IS STRAIGHT/ROUND AND GOOD COLLETS). Please see Adjustable Collets under the product categories.<<<<
Please Note: All of our spindles are custom ground, hardened and balanced. It takes about 2-4 weeks build time depending on stock and demand.
