Allied Machine & Engineering Corp. presents its Guided T-A and 3XL drilling systems for deep-hole drilling applications. The two systems provide predictable and confident deep-hole machining and tool life increases of up to 50 percent with inserts available in the high-heat-resistant AM200 coating, according to the company.

Guided T-A provides for tighter, true position and a straighter hole throughout the operation, providing penetration rates of up to twice that of a gundrill. Engineered for breaking out on uneven surfaces, Guided T-A is available in carbide-clad and chrome-plated styles and can be used with standard T-A and GEN2 T-A, HSS or carbide blades.

3XL, the longest of the T-A style holders, is available in helical or straight flute designs; lathe, Morse taper, or Flange style shanks; and lengths from 1xD up to 28xD (stocked).
