Most Jigs available today are made from aluminum. Modulus Arms standard duty Jigs are made from aluminum and our Heavy-Duty Jigs have high-strength steel for all wear surfaces. To further enhance the longevity and ease of use of the Modulus Arms Jigs we have developed the Patent Pending Speed Drill. The Speed Drill is designed to work with every of Modulus Arms Jig including the Heavy-Duty AR-15, Standard AR-15 and AR-308/ AR-10 Jigs. 

The Speed Drill is designed to drop into the standard 3/8" holes in Jigs available from most vendors and provide a wear resistant high-strength steel collar that allows you to drill a smaller 1/4" pilot drill hole and follow it with the 3/8" drill bit with virtually no effort. This dramatically cuts down the time it takes to finish a lower receiver and improves the longevity of the Jig. It also provides more accurate drilling since you are using the 1/4" drill bit to align the hole placement and the 3/8" drill chases easily.

The Speed Drill is designed to make the finishing process with a standard hand held drill easier and faster. It cuts the drilling time in half and removes virtually all the wear from the Jig Drill Template. The Speed Drill is compatible with Drill Presses as well but the biggest advantage comes from those using a hand held drill.

If you are finishing your lower recevier with a Modulus Arms or competin Jig using 3/8" holes and a hand held drill, you will be glad you have the Speed Drill.

    The drill guide makes drilling of the lower receiver faster and more precise. The smaller surface of the 1/4" drill bit penetrates the material of the lower receiver faster leaving a nice straight hole for 3/8" bit to finish the hole to full size. The drill stop assure the bit stops at the correct depth. This is a must need item if you are using hand drill.

  2. Great Idea 5 Star Review

    Great on drilling the 3/8 holes to have a reducer guide so you can drill1/4 pilot holes straight

    Even though I used my 1/2 hp drill press I also used the speed drill to save wear on the drill block.
    Once you use the speed drill the 3/8" drill finishes the cut very easily.

  4. Drill guide 5 Star Review

    Years ago I was a tool and die apprentice. We made jigs for various companies and using aluminum with some type of hardened steel was common. It's cheaper to replace a drill than the whole jig or fixture.

    Very accurate depth gauge with the drill bit stop attached for milling and drilling out your 80% lower

  6. must have for handrills 5 Star Review

    Posted by on 23rd Aug 2016

    The speed drill collar works great. I think it is a must have if you are using a hand drill. I have a small coreded handrill and using the speed drill made quick work is the 7075 lower.

  10. speed drill kit is amazing 5 Star Review

    Posted by on 27th Mar 2016

    Great idea, takes a little longer with the extra steps but well worth it. Saves the jig big time, drilled one lower and never scratched the jig. Will buy again.

  11. working good 4 Star Review

    Posted by on 15th Mar 2016

    I've only used this once, but it cut down my drill time and effort considerably. Only knock I really have is shipping prices. For something this small, shipping should not be 50% of the item itself

  12. Works as advertised 5 Star Review

    Posted by on 22nd Feb 2016

    It really works well and makes using a hand held drill as fast as a drill press. I'd say it approximately cuts the time to drill the 3/8" holes in an 80% lower in 1/2 as compared to using a 3/8" bit alone. The 1/4" hole with the speed drill kit drills fast and easy and the bit never touches the actual jig and then drilling the 1/4" hole out to 3/8" goes super fast and easy so it basically shouldn't wear the drilling plate in the jig much at all.
