Why Not All Drilling Grease Is the Same

Posted by Rod McCoremick on Dec 12, 2017 11:00:00 AM

Any diamond driller reading this blog regularly knows how often we discuss the importance of using drilling lubricants, grease and thread compounds. These products help preserve and extend the life of your drilling equipment. But not all products are the same and we like to recommend products that we know are high quality and will make a difference in either efficiency or cost savings.

Why You Need a Water Heater in Diamond Drilling

Posted by Rod McCoremick on Nov 20, 2017 10:30:00 AM

It doesn’t really matter where you are performing diamond drilling, when winter hits, drilling can become problematic because of the cold. You don’t have to wait until you hit the middle of winter to start thinking about how you will deal with freezing temperatures. If you are in the northern hemisphere, it is right around now that you should be thinking about getting a water heater if you don’t already have one.

EXPLO 220 Geotechnical Drill Rig Hits Success in the Big City

Posted by Rod McCoremick on Nov 6, 2017 3:30:00 PM

One of the differences between mineral exploration and geotechnical drilling is the fact that with geotechnical, drilling is often done in urban areas. This type of drilling often involves construction or repair of structures where the ground conditions need to be tested for stability, pollution or other issues.

A New Geotechnical Drill Rig with Muscle

Posted by Rod McCoremick on Jul 31, 2017 2:30:00 AM

I’ve got a new product to announce for our friends in geotechnical drilling: the GT8 rig from Versadrill. We recently got to try out this new hydraulic, geotechnical drill rig on our premises and shot a video so we could give you all a first-hand view of what it looks like, how it operates and what it can do.

How to Choose the Size of Your Reaming Shell

Posted by Rod McCoremick on Mar 27, 2017 11:00:00 AM

I have noticed that there are a lot of drillers who use the 6 inch reaming shell pretty exclusively, so in this blog I wanted to talk about the other sizes available and how to know when you should use another size. Reaming shells are used to maintain the diameter of the bore hole and to make sure other drilling equipment does not get stuck down the hole. The outside surface of the reaming shell has natural and synthetic diamonds embedded in a resistant matrix.

Reaming shells come in 6, 10 and 18 inches. How do you know when do you use each size?

Choosing Core Bit Configurations: Discharge Options

Posted by Rod McCoremick on Feb 27, 2017 11:15:00 AM


In this blog we will continue to try and demystify how to choose a core bit configurations. A few weeks ago, we tackled the role of waterways and now we will look at discharge options. Remember that picking the right core bit is an important decision that impacts drilling performance and you need to consider several variables.

The Role of Waterways in Configurations: 3 Factors to Consider

Posted by Rod McCoremick on Jan 23, 2017 10:30:00 AM

Choosing a core bit configuration has always been considered to be a bit of a mystery, right up there with how to choose the right core bit. Because there are so many to choose from, drillers usually stick to a few of their favourites for as long as they provide good performance. When performance starts to suffer, they need to try something new.

Fundamental Guide to Choosing the Right Core Bit Configuration

Posted by Rod McCoremick on Dec 12, 2016 10:30:00 AM

The question we hear most often from customers is “how do I choose the right core bit for the ground I will be drilling in?” So last year we wrote a guide on that and it was very popular. Many variables need to be considered including rock hardness, the variability of the rock, and whether it was abrasive, and then you need to choose the right bit range and configuration. While we have scratch tests to help determine bit range, how do you choose the configuration?

5 Precautions to Take When Setting a Wedge

Posted by Rod McCoremick on Oct 10, 2016 10:30:00 AM



No matter how carefully you planned and drilled, bore holes are rarely straight. Many things can have an effect on the direction of the hole, such as weight on bit, poorly set up drill rig, fractures or voids in the ground formation, bedding planes, or ground that goes from hard to soft. Too often, the path of the bore hole needs to be corrected in order to reach a desired target and that is when you should consider using a wedge.

Time To Go Fishing – 4 Ways to Recover Your Drill Rod

Posted by Rod McCoremick on Oct 3, 2016 10:30:00 AM


A surefire way to stall operations and lower productivity is to break a drill rod in a bore hole – a too common occurrence in diamond drilling.

A rod string can break, either from too much pressure or by being dropped, or the bit can melt and fuse to the rock. Certain ground conditions can lead to your equipment being jammed. Clay can swell enormously when water is introduced and this swelling can trap the rod and drill bit. Coming across sand can also be harmful as the sand can collapse around the drilling equipment.
