Drilling

Small-Caliber Gun Barrel Processing Cell

A cell is typically composed of three machines. First, Precihole’s four-spindle gun drilling machine permits deep drilling of four barrels simultaneously. An open machine configuration facilitates robot access, minimizing operator involvement and supporting 24/7 operation. Depending on individual model configuration, the machine can drill IDs from 0.04" to 1.57" and barrel stock from 0.4" - 4.0" OD.

TwistSFeed Drill Family

TwistSFeed reduces costs by improving tool life as well as achieving higher productivity due to multiple flutes along with new IN2205 coating designed for steel and cast iron applications. The clamping mechanism allows for the simple replacement of drill tips as well as accommodating multiple tip diameters per drill body facilitating economical stock management for end users.

AH9130 Grade for DrillForce-Meister 

AH9130, consisting of a PVD coating layer optimized for drilling applications with a dedicated carbide substrate, is the latest insert grade specifically developed to provide significant tool life improvements and more predictable wear patterns in hole making applications of ISO P (steel), ISO M (stainless steel), and ISO K (cast iron). 17 SMP-style inserts have been released in the latest grade, covering diameters from 20.0 mm to 35.0 mm (.787″ to 1.378″). In addition to Tungaloy’s versatile grade AH725 which covers most ISO materials, AH9130 provides DrillForce-Meister with added process security and tool life improvements in ISO P, M, and K applications.
