Blast Media
  • For cleaning, deburring, finishing, and peening applications. Round, smooth media leaves a peen finish. Sharp, jagged media leaves an etched or matte finish. The harder the material, the deeper media will penetrate and the faster it will work. Spherical shape is ideal for use on soft materials where tolerances must be maintained. Contains no free silicas and leaves no residue.
  • Corn Cob Abrasive
  • Biodegradable organic media removes surface contamination, debris, and coatings with minimal or no damage to the targeted surface. Use on wood and softer surfaces.

Drillspot tripled the price of this item to the point that it is no longer worth buying. The product is fine but the price is dumb.

The price is terrible.

Not so fast

Wednesday, March 20, 2013

Bought from here because of all the reviews about fast shipping. That was NOT the case on my order. Took them 3 days before they shipped, and they shipped to Florida from California. Took over a week for me to get my stuff. Would have went a different route if I knew this.

Sounds good, if I ever receive it

SLOW shipping

The corn media was just what I needed for cleaning brass. My old corn media was over a year old and really dirty. The new media cut my tumbling time in half and is much cleaner. Drillspot shipped it the day it was ordered and it arrived the next day. Outstanding!

perfect for reloader

Thursday, January 03, 2013

I finally was able to retire and spend my time at my favorite hobby, punching paper with handguns and rifles. Started reloading all of my handgun and rifle brass. I tried the Lyman corn cob media but found it annoying when it constantly stuck in the primer pockets. Next I tried the finer grit "Zilla" walnut shell grit from the pet supply store. That worked better but didn't leave me with a brightly polished finish on my brass. Used this product with some Nu Finish car wax and some Lyman media charger and got what I had hoped for, a polished mirror like finish and clear primer pockets. When sizing rifle brass like the .223, the polished brasswith Red ding case wax makes full length resizing a breeze. I tumble the brass along with some strips of cloth that has the Red ding was on them in a cheap Harbor Freight rock tumbler to coat the brass. Between the high polish and sizing wax, never a stuck case. Next day delivery too:)

Perfect for the reloader. Did I mention I received it the next day after ordering:)?

For my use, this is a dream product!!

I use this to tumble fired rifle casings before reloading them. It works perfectly and is the cleanest and lowest cost media I can find. The service from DrillSpot is amazing. It arrived in 2 days! Great job, guys.

The only thing I would change is to put it in a plastic bag to keep it dry during shipping & storage.

Great Tumbler Material for Birds!

Tuesday, November 27, 2012

I purchased your corn cob grit hoping that it would be a good medium for tumbling birds for taxidermy. As I had hoped, it works great. The grit was well-packaged and arrived FAST!!! I saw the other posts on the quick shipping but didn't think that it would be that quick for me up in Montana but it was! I'll definitely purchase again. Thanks!

Recent purchase

Tuesday, November 27, 2012

I recently read some reviews about the Corn Cob media sold by Drillspot and its use as a cartridge case cleaner. I placed an order for the media, and as stated in the reviews it was promptly received in just a couple of days. Even though I have yet to use the media to clean any cartridge cases, I wanted to give a big thumbs up for the reasonable price of the product and the fast shipping.

Ordered on Easter Sunday and it was delivered FedEx Tuesday afternoon. I really love the price with shipping included, but I really respect a company that will get my order on the truck that fast on a holiday. 40 pounds is a lot of corncob too. Box was heavier than I expected, after filling the first 5 gallon bucket and trying to find another with a lid you realize just how much there is.

Corn Cob for Tumbling

Tuesday, January 17, 2012

This product was found on the internet and was listed on other sites for up to $2.30 per pound plus shipping. Then I was refered here and found the price to be around $26.00 for 40# with free shipping. I jumped right on it. Great product for tumbling brass, clean, and small enough not to wedge in primer pockets. I reload several thousand rounds a year and this is enough to last several years.

Shipping cost and shipping speed was superb!

Fair For Cleaning Brass Cartridges

Tuesday, December 13, 2011

I would rate this product fair for cleaning brass cartridges. This 20/42 grit, I believe is too fine and generates static which allows the grit to cling to the brass. I think next time I'll order a larger size.

This 20/40 is ideal for polishing cartridge cases. It's like a coarse sand, so it will flow through most flash holes. I've always used walnut, but I gave this a try and was pleasantly surprised. Drillspot's service and shipping is second to none. Was at my door two business days after ordering. Great product, price, and service.

When you see 40 pounds online, it looks different than 40 pounds in real life. I guess all I needed was a coffee can full. I am probably set for quite a while! Got a good deal, though, right?

Great Experience

Tuesday, September 13, 2011

A VERY fine grit, more so than I thought it was going to be. I could probably go a size coarser actually. I use this for tumbling brass and wanted to get something fine enough so that it didn't get stuck in flash holes and the necks of .223 rifle cases. Mission accomplished. I bought this with the normal, free shipping. Got it the next day!

How fine grit it was. No problem getting stuck in cases.

I might like it to be slightly coarser as this is a little dusty.

20/40 media

Monday, May 02, 2011

I ordered online Monday morning and my order was waiting on the porch when I got home from work Tuesday evening. I am amazed by this. The product was as described in every detail. Overall, I'm extremely satisfied with my purchase.

I am using this product to clean/polish cartridge brass for reloading. It is highly suited for this as it's granulation allows it to flow right through the flash hole without getting stuck thereby saving me alot of work picking it out of each and every case.

The only thing I could think of to make this more suited for the use I put it to would be to offer the option of being pre-treated with some sort of polish. Since I am using this product in a manner it was probably not intended for I realize this probably isn't something that's likely to happen.

Product arrived within 3 was exactly as expected. Price for bulk is far cheaper than the smaller amounts sold at gun stores and websites. And, no postage. The gun websites charge as much for S&H as for the product itself. With a little Flitz brass cleaner and the cobb media and a few extra hours of vibrating, your brass will gleem like new.
