Description

The TTC 01-135-125 is a heavy-duty, high-performance high-speed steel (HSS) taper shank twist drill bit engineered explicitly for cutting extra-deep holes in demanding structural environments. This fractional 1-1/8" drill bit features a precision-machined #4 Morse Taper (4MT) shank, ensuring seamless integration into stationary machinery and heavy radial arm drill presses equipped with standard taper socket spindles. Boasting a robust 118-degree normal point angle and an extra-long 18-inch overall body profile, this cylindrically ground tool maximizes chip clearance through deep bores while offering exceptional rigidity. Coated in a rugged black oxide finish, it provides superior surface lubricity and heat dispersion when drilling into tough steels, alloy metals, cast irons, and non-ferrous substrates. [1, 2, 3]
⭐ Key Features & Benefits
  • Extra-Long 18" Drill Profile: Features a massive 12-inch flute length coupled with an 18-inch overall span to clear extra-deep industrial holes effortlessly. [1]
  • Industrial #4 Morse Taper (4MT): Rigid taper profile wedges seamlessly into standard spindle sockets, fully eliminating chuck slippage under maximum machine torque. [1]
  • 118° Universal Point Angle: Optimized geometric point excels across general-purpose industrial setups, making short work of diverse metals. [1, 2]
  • Hardened High-Speed Steel (HSS): Machine-forged to a rigid 58 to 60 RC structural hardness rating, preventing premature edge degradation and structural deflection. [1]
  • Protective Black Oxide Coating: Resists thermal breakdowns, retains crucial cutting fluids at the tip, and prevents sticky chip weldment during continuous feed cycles. [1]
🔧 Uses / Applications
  • Deep Hole Drilling Layouts: Specifically optimized for drilling high-depth channels in heavy metal plates, weldments, and commercial structural workpieces.
  • Machine Shop Production: Designed for stationary machinery, boring mills, lathe tailstocks, and heavy radial arm drill configurations.
  • Multi-Material Fabrication: Slices through alloy steel, cast iron, structural non-ferrous plates, and thick mechanical plastics.
  • Maintenance & Rig Rebuilding: Ideal for structural fleet retrofits, custom industrial tooling setups, and commercial machinery overhaul projects. [1, 2, 3]
