ISO Designation Breakdown

Engineering Dimensions & Geometry

Grade Details – Key Grade Characteristics

The TX grade represents Kyocera's premium micro-grain carbide technology, specifically developed for high-speed drilling in ferrous and non-ferrous materials. Key characteristics include:

• Substrate: Micro-grain carbide with 0.8 μm average grain size for optimal hardness and toughness balance
• Coating: PVD AlTiN multi-layer PVD coating with hardness of 3,300 HV
• Oxidation Resistance: Stable performance up to 1,100°C (2,012°F)
• Coefficient of Friction: 0.35–0.40 against steel, reducing built-up edge formation
• Coating Thickness: 2.5 ± 0.5 μm for minimal edge radius impact
• Color Code: Bronze-copper appearance for quick visual identification

Grade Comparison Matrix

Chipbreaker Profile

Although this is a solid carbide drill rather than an indexable insert, the cutting edge geometry incorporates advanced chip control features:

• Split Point Geometry: 140° point angle with web thinning reduces thrust force by 40% compared to conventional points
• Parabolic Flute Design: Deep, polished flutes provide maximum chip evacuation capacity, essential for cast iron and carbon steel applications
• Margin Relief: Secondary margin land reduces friction and heat generation during full-depth drilling
• Edge Preparation: Controlled hone of 0.002–0.003" (0.05–0.08 mm) prevents micro-chipping on entry while maintaining sharpness
• Coolant Channels: Internal coolant ports direct high-pressure fluid to the cutting edge for effective chip flushing and thermal management

Recommended Applications & Workpiece Materials

Application Map by Operation

Recommended Cutting Conditions

Parameters below are starting recommendations for cast iron using flood coolant or through-tool coolant (minimum 70 bar / 1,000 psi recommended for 19/64 diameter):

Operating Guidelines

• Entry Angle: Ensure perpendicular entry (±1°) to prevent corner chipping. Use a spot drill or center drill if hole depth exceeds 5×D.
• Peck Cycle: For depths beyond 2×D, use a full retract peck cycle every 0.445" to clear chips and allow coolant penetration.
• Rigid Setup: Minimize tool overhang to 4×D or less. Use hydraulic or shrink-fit holders for best runout (<0.0002" TIR).
• Speed & Feed Ramping: Ramp spindle speed over 2 seconds on engagement to avoid thermal shock to the carbide substrate.
• Coolant Filtration: Maintain coolant cleanliness at 25 μm or finer to prevent abrasive wear on the cutting edges.
• Tool Life Monitoring: Replace drill when flank wear reaches 0.008" (0.20 mm) or when surface finish degrades below 32 μin Ra.
• Breakthrough Strategy: Reduce feed by 20% when drill approaches breakthrough to prevent burr formation and exit chipping.

Toolholder Compatibility

Collet Size Recommendation: For 19/64" (0.2969") diameter, use a 0.297" precision collet (ER16 for shanks up to 3/8", ER20 for larger). Ensure collet clamping force is within manufacturer specifications to prevent slippage under high torque.
