I suspect that China is making some mag drills that are similar. I've used it about 30 times and it works just fine and hasn't tried to kill me like the high end drill did. So soured on high end core drills, I bought a $300 core drill to drill a couple of 4' holes through 6' reinforced concrete. Clutch didn't work on the brand new rental drill and it about broke my wrists / arms / collar bone. The material, length, and geometry of each bit as well as any coating or surface treatment that is applied to it will affect its.

They install into equipment such as handheld drills, drill presses, or CNC machines. The local rental place rents expensive high end Husquavas. Drill bits have cutting edges that remove material as the bits rotate to create holes in a workpiece. I also pleasantly surprised myself with China special core drill on Amazon a few years ago.

I have a Hougen HMD904 and it would be more than adequate for the job. And you get the primal feeling of POWER when you pull down hard on the handle and hear the motor slow down a little. In my time with mag drills, it usually takes longer and more effort to get the drill positioned than to drill the hole. I think 150 7/16' holes through 3/4' is going to go quickly and not need power feed. P.S., do get a unit that takes annular cutters (3/4 weldon spindle), and a auxiliary Jacobs chuck, so that you can use the slugger bits in the future when drilling larger holes! I don't have a specific brand/model recommendation but make sure it has the upward travel to fit the chuck and the 7/16 twist drill.

It would make sense is if you were set up drilling larger holes with a mag drill, and had a few 7/16 to do as well. I don't know what size the slug is on a 7/16 slugger, but it can't be much more than 1/4 or so, meaning you are saving the effort of drilling a 1/4' hole. that advantage is basically lost under 1/2', and they cost a lot more too.Īs a way of visualizing the work savings, the size of the slug is a good guide. The big advantage of annular cutters is they remove less metal for a given size hole than a twist drill, and take proportionately less feed pressure. the annular cutter will dull really quickly on scale or rust, and resharpening one isn't nearly as easy as is a twist drill.

Stop fumbling around looking for the right bit, your cutter set will be well organized.You really don't want to use an annular cutter if you are drilling hot rolled or rusty plate at 7/16. It features a comfortable handle, allowing convenient transportation and quick classification.
