ARCHIVE Rogue Drill Press Reduction kit – 1:2 and 1:4 ratios available

[RogueFab]

Does your drill press run too fast to use a hole saw on metal? How about a ¾” drill bit through steel plate? Are you sick of burning up expensive cutting tools? Look no further, you have found the solution. Now you can turn a used $150 drill press into a serious cutting machine!

This bolt on kit cuts the RPM of your drill press and increase torque. Typically referred to as a “jackshaft”, these are commonly home made with plywood and hardware store parts. This is a much easier and safer alternative, and will likely cost you less money than building your own. Made with high quality greasable ball bearings in cast pillow blocks with a laser cut and CNC formed steel mount, this tool is designed to last as long as your drill press when properly cared for. Requires trimming your belt guard if equipped. kits reuse one of your factory belts (or an additional belt will be required). Comes with new motor mounting hardware. Made in the USA*.

NEMA 56 3L 1:2 – 3L (3/8”) belts, 1/2 the RPM, 2x torque. $119 shipped (US)

NEMA 56 3L 1:2 – A (1/2”) belts, 1/2 the RPM, 2x torque. $119 shipped (US)

NEMA 56 3L 1:4 – A (1/2”) belts, 1/4 the RPM, 4x torque. $139 shipped (US). Coming coon!

What is a NEMA 56? These kits work only with motors that mount with a 3" x 4 7/8" bolt pattern and have a 5/8" shaft, part of the definition of a NEMA 56 motor. Most drill presses have these motors. Call/PM us if you think you have something else.

We have the parts on order for the 1:4 kits, and we got the price improved considerably! $139 shipped in the US!

And you can double these kits up, mounting one off each side. We have longer hardware and we will be carrying longer belts too. Now with one kit you can go down to 1:2 or 1:4, and with 2 kits you can crawl a 3" hole saw or a mill cutter at 1:8 or 1:16!
Even if your drill press will only slow down to 600 RPM from the factory, you can rip it up at 37.5 RPM without any load on the spindle!

Here is an image out of our CAD system with the 1:4 pulley installed on factory 12 speed benchtop drill press.

I haven't looked under the cover lately, but I seem to recall my less-than-professional-grade Craftsman press doesn't have the idler pulley between the motor and the spindle (yes, its WAY too fast for hole saws in steel)... I assume I cannot use this kit?

That is also pretty common, and your factory belt should fit just fine Sorry we don't have a pic of a 2 pulley drill press. Until we get one installed, this rendering will have to do. If your pulleys are between 10 and 20 inches apart, you can set up this kit with less than a 1" difference between the original OEM belt path and the new belt path to the reduction kit. Your factory tension adjustment should accommodate the small difference in pulley spacing. If it doesn't, you will have to go buy a $6 belt.

Your press is probably a 3600 RPM motor (they are usually less expensive than 1800 RPM ones), and I'm guessing a 5:1 reduction max, for about 720 minimum RPM. How would you like to get that baby below 200 RPM for less than $150?

Here is a rendering of an 8" pulley, good for a 1:4 reduction on your drill press.

Close enough - its a 5 speed w/ a 3100rpm motor. Factory reduction max reduction is 5:1.

Is what you're showing there with the 8" pulley available already or a future development?

Order placed for a 1:4. I am looking forward to this upgrade.

Your order shipped this morning, you will have it on your doorstep in 2-3 days. Thank you kindly for the business sir.

Any way to distinguish a NEMA 56 motor?

I have a Delta press and am interested in the 1:4 set up.

 

[RogueFab]

Wheelingnoob,

There are two ways to tell:


1. The motor will have a 56 or the words NEMA 56 printed on the info plate.


2. Measure the bolt pattern where the motor attaches to the press. The bolt spacing will be about 5 inches horizontally and 3 inches vertically. Also measure the output shaft. It will be 5/8 inch. If you havetheright shaft dia and bolt pattern, it will work.

It is Cyber Monday! We are offering free shipping on all orders over $1000 and $25 off shipping on all other orders over $100. Discount is given as a refund after purchase. Kick off the online shopping season with new tools from Rogue Fabrication!

We added the key features that need to match on the motor for compatibility to the original post-

"Works only with motors that mount with a 3" x 4 7/8" bolt pattern and have a 5/8" shaft."

We can make them for other motors (like stuff over 1 HP). Just give us a call or PM.

This big Rockwell drill press (equipped with a RogueFab Reduction Kit) is used by Spiral X LLC, in Garland, Texas. Spiral X makes industry leading high performance air coolers, and drills thousands of large diameter holes in stainless steel every month. Brian (the owner) said: "The drill press reduction kit is working fantastic. I don't know how you would drill into stainless steel in production without it. We were able to pull in the drilling we used to outsource (although we are a little slow). For instance, on a piece I was paying $50.00 for, we are doing the drilling in 1 hour with a jig internally, saving jobs and of course money!"

Here is a good resolution photo of just the reduction kit. 1:4 shown, although we just got in some slightly smaller pulleys and got it stretched down to almost 5:1!

 

[RogueFab]

We just found a smaller pulley for the motor side of the 4:1 kit, now they are 5:1!!! Same price

 

[RogueFab]

We offer custom solutions on these kits too. If you have an interesting set up that doesn't look like a regular drill press, chances are good that we can find a way to slow it down with out kit still!

We just sold a double kit, 10:1 reduction. Customer could have gone up to a 25:1 reduction, but it would have been TOO SLOW. How often do you hear that about a drill press?
Some of our customers have been asking us about belt speed reduction versus VFD (variable frequency drive). VFD uses power signal adjustments and a 3 phase motor to infinitely vary the speed. The two main drawbacks are cost and torque. VFD requires a new 3 phase motor and the VDF box(expensive for most people) and is a constant torque system. When you cut the speed at a 5:1 ratio, you get no more torque. With belt reduction, you get 5X the torque. Both methods have their advantages and drawbacks.

 

[RogueFab]

Still have orders coming in, thanks for the business everyone! Save yourself hours in the shop making some way to do this and buy our kit!

Another batch of our Drill Press Reduction Kits ready to be shipped out to customers. If you haven't looked these up on our web page and you drill metal, you owe it to yourself to take a look. They will pay for themselves in burned up drill bits!
