DrillMeister 12xD Drill Body Head Changeable Drills

Tungaloy’s DrillMeister line of head changeable drills now includes a new drill body in a length-to-diameter ratio of 12xD. 

DrillMeister incorporates a unique self-locking interface that enables simple and secure drill head exchange. Since drill heads can be replaced without having to remove the drill body from the spindle, tool setup time can significantly be reduced, eliminating presetting, offset, and touch-off of the replaced tool. 

The new 12xD drill body will cover drill diameters from 23 to 25 mm or from .394″ to .433″. The drill body has high helix helical flutes that are optimized to efficiently remove chips from the cutting point to the outside. This enables higher feeds and speeds as well as exceptional machining reliability. The DMC style drill head is a good option for high precision and efficient deep drilling; its optimized margin design and self-centering capability provide high hole precisions without the need for a pilot hole, significantly reducing cycle time during deep hole applications. 

The new drill body features a cylindrical shank that is precision-ground with no flats. This ensures close runout accuracy and high torque transmission when clamped with a full surface contact in a high-precision collet chuck, milling chuck, or hydro-chuck holder. 

At a Glance: 

  • Drill diameters: 23 mm to 25 mm or .394″ to .433″ in a length-to-diameter ratio of 12xD
  • High helix helical flutes ensures efficient chip evacuation during deep hole applications
  • Unique self-locking interface ensures easy and secure head replacements
  • Enables high precision deep hole drilling with the same precision achieved with solid carbide drills
  • Ideal for the use with a high-precision collet chuck, milling chuck, or hydro-chuck holder

Related Glossary Terms

  • chuck


    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • collet


    Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.

  • flutes


    Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • shank


    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
