Tungaloy has added 35xD, 40xD and 45xD drilling depth capabilities to its DeepTri-Drill indexable insert deep hole drills.
DeepTri-Drill is designed to provide productivity and application security for drilling deep holes on standard machining centers and CNC boring machines, while ensuring easy tool management by eliminating the need for regrinding. The insert features chip splitters that allows effective chip evacuations enabling extremely high feed rates during deep hole drilling in various materials. High productivity and process reliability can be attained in deep hole drilling operations. Inspired by BTA deep hole drilling technology, innovative insert geometry and optimal guide pad allocations on the drill body allow DeepTri-Drill to produce high quality deep holes equivalent to those made with traditional brazed gun drills.
In addition to the current lineup ranging up to 25xD, DeepTri-Drill now offers 35xD, 40xD and 45xD drill depths, further expanding its deep hole drilling potential similar to those found in injection mold and large-sized component manufacturing.

Related Glossary Terms
- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- indexable insert
indexable insert
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
