The term diamond core drilling comes from the 'diamond bit' drill used during this process. This drill bit is made up of a group of small, industrial-grade diamonds set into a metallic, soft matrix. As the ground is drilled this matrix will wear away and expose more diamonds.
Core drill bits are specifically designed for cutting precise circular holes in most construction materials like brick, stone, concrete and masonry. Made from steel, the diamond core drill bit comes in many lengths and has various sized teeth depending on the material and cutting requirement. With a hollow centre, the cut material will remain ...
Later test pits and mining operations checked the drill sampling within 0.005 per cent, in carbonate ore and 0.05 per cent, in sulfide ore. A bit recovering a 1 1/8-in. core was used. The choice of sampling methods must depend on the engineer's judgment of the character of the material to be sampled.
Typical ground formations in this region are 70 percent iron ore, with bands of chert that are very hard and abrasive. These conditions require a very free cutting bit to stay sharp and achieve good production, as well as an abrasion-resistant matrix to attain acceptable bit life.

Drilling Parameter Notes 1. All dimensions, weights and volumes shown are nominal 2. Rotation Speed: in extremely broken, hard, ground, run at half RPM and weight on bit (WOB) sufficient to reach 1 - 2 ipm (3 - 5 cpm). 3. WOB: Constant WOB on bit will require changing holdback pressure. Check off bottom weight as rods are added. 4.

In the Lake Superior iron-ore districts a combination diamond- and churn-drill machine, known as the Mesabi rig, has been used extensively. When drilling is done in soft formations that will break and thus not return a core, vertical holes may be drilled with a chopping bit screwed on the end of the regular string of rods.

This line of bits in particular are called Ultramatrix (UMX) diamond core bits. The family of UMX bits is designed to drill efficiently in both soft and hard ground. The 07UMX bit is chosen to handle anything from limestone to taconite (3 to 8 on the Mohs scale of mineral hardness) and the 09UMX tackles slate to iron ore (4 to 9 on the Mohs scale).
