WHAT IS DEEP HOLE DRILLING ?
HTT has being dedicated in deep hole drilling for over 25 years. We offer a full line of deep hole drilling machines with tailored made specifical fixturing and machine configurations to meet customer applications and requirements. You can contact us for information about our deep hole drilling machines. Deep hole drilling is where the hole depth to diameter can be upto 400:1 ratio. Deep hole drilling consists of two techniques: Gun Drilling & BTA Drilling.

Gun Drilling

More >>
Gundrilling is a deep hole drilling process that uses a long cutting tool to produce holes in metal at large depth - to - diameter ratios. Gun drilling is effective in diameters from 1–50 mm[0.04–2.00 in].A gundrill tool differs from a conventional twist drill by its unique shank and head geometry; a standard gundrill has a V shape groove to flash our chips and oil with built in coolant hole in the tool.
 

BTA Drilling

More >>
BTA drilling is a deep hole drilling process that uses a specialized drilling tool on a long drill tube to produce deep holes in metal, from holes with a diameter of 20 mm [0.80 in] and larger, up to depth-to-diameter ratios of 400:1. BTA drilling is the most effective method of drilling deep holes, as it is a cleaner, more reliable and capable process than conventional twist drills, and can achieve larger diameters and higher feed rates than the alternative gundrilling.
