Product Overview

The Kyocera #12 DRILL 2FL TA SGS56221 is a premium solid carbide drill engineered for high-performance CNC machining. Designed with a AlTiN-coated ultra-fine grain carbide (0.5 μm), this tool delivers exceptional wear resistance, thermal stability, and dimensional accuracy across demanding production environments. The optimized 2-flute geometry ensures efficient chip evacuation and reduced cutting forces, making it ideal for precision hole-making operations in cast iron, ductile iron, grey iron.

Application Map by Operation

OperationSuitabilityNotes
Through-Hole Drilling★★★★★ ExcellentOptimal chip evacuation with 2-flute design
Blind-Hole Drilling★★★★☆ Very GoodUse peck cycle for depths >3×D
Counterboring★★★★☆ Very GoodReduce feed by 20% for best surface finish
Spot Drilling★★★★★ ExcellentSelf-centering 140° point angle
Micro-Drilling★★★☆☆ GoodRequires rigid setup and high-pressure coolant

Cutting Speed (V_c)40 – 100 m/min60 m/min
Feed per Revolution (f_n)0.05 – 0.20 mm/rev0.10 mm/rev
Depth of Cut (a_p)Up to 2.0 × D1.2 × D
Coolant Pressure20 – 70 bar (recommended)40 bar
Coolant TypeEmulsion (8-10%) or MQLEmulsion with EP additives

Operating Guidelines

  • Runout: Maintain spindle runout ≤ 0.01 mm for optimal tool life and hole quality.
  • Peck Cycle: For holes deeper than 3×D, use a peck depth of 1–1.5×D with full retract to break chips.
  • Entry Angle: Ensure perpendicular entry (±1°) to prevent chipping of the cutting edges.
  • Coolant: High-pressure through-spindle coolant is strongly recommended for holes >2×D.
  • Pre-Drilling: Not required for standard applications; tool is self-centering with 140° point geometry.
  • Speed/Feed Ramp: Ramp up to full cutting parameters over the first 2–3 holes to avoid thermal shock.
