• Machined from solid hardened and tempered high tensile steel.
• Machined to suit strata conditions.
• Positive, Negative and Neutral Rake angles.
• PCD diamond for difficult drilling.
• Threaded drive, Square drive and RE drive shank combinations available.
• Sizes from 27mm – 44mm in M16 drive. This offers a considerable cost and time advantage as 22mm hex drill steels can be used for holes up to 44mm in diameter.

• Manufactured from solid homogeneous heat treated bar.
• High tolerance / high output capability.
• Low cost.
• Machined seat for carbide insert.
• Patented technology for manufacture.

• No wing breakage.
• CNC precision tolerances.
• Faster drill penetration rates.
• Better carbide adhesion to machined tip seat.
• Reduce reject volumes.

• Rake angles and other dimensions can be altered to suit drilling conditions.
• These R & D bodies can be produced in low quantities for a fraction of the cost associated with investment casting.
• Reduce production costs.
• Increased profits.

The results of our independent testing show that generally when a roof section is being bolted the operators of the drill rig have reduced the penetration speed of the drill. This is done to minimize the risk of drill failure. Our testing shows that a reduction in penetration rate is not necessary due to the increased strength of our bodies. We now have drill body technology available that is compatible with today’s carbides and drilling machines.
