Product Overview

The Kyocera 13/32 3FL 5XD TM SGS55183 is a premium solid carbide drill engineered for demanding CNC machining environments. This 3fl-flute design with 5XD length-to-diameter ratio delivers exceptional hole quality, dimensional accuracy, and extended tool life across a broad spectrum of workpiece materials. Manufactured in Japan to exacting tolerances, this drill combines an optimized substrate with an advanced PVD coating to withstand high cutting temperatures and maintain edge integrity under aggressive cutting parameters.

Whether you are drilling through-holes in structural steel or precision blind holes in stainless steel components, the TM grade substrate and specialized point geometry ensure consistent chip formation, minimal burr, and superior surface finish. The tool is designed for modern machining centers with through-spindle coolant capability, maximizing productivity in unattended operations.

Grade Details — Key Grade Characteristics

The TM grade is a Kyocera proprietary carbide substrate developed specifically for solid round tools. It represents the culmination of advanced powder metallurgy and coating technology to deliver a tool that excels in both productivity and reliability.

Exceptional wear resistance and thermal stability. Optimized for high-speed drilling with internal coolant delivery.

Grade Comparison Matrix

Chipbreaker Profile

The flute profile of the 13/32 TM has been engineered with a wide, open-groove geometry that accommodates large chip volumes while maintaining core strength for 5×D drilling depths. The three-flute configuration divides the chip into three manageable segments, reducing the load per cutting edge and enabling feed rates up to 30% higher than conventional two-flute designs. The polished flute surface (Ra < 0.4 μm) minimizes chip adhesion, especially critical when machining stainless steel and other ductile materials.

Application Map by Operation

Recommended Cutting Conditions

The following parameters are starting recommendations. Adjust based on machine rigidity, workpiece material condition, and coolant delivery efficiency. All values assume stable fixturing and proper toolholder condition.

Important: For 5XD drilling, reduce cutting speed by 15–20% and use peck drilling cycle (Q ≤ 31 mm) if coolant pressure is below 70 bar (1,000 psi).

Operating Guidelines

• Runout Control: Maintain total indicator runout (TIR) below 0.01 mm at the tool point. Excessive runout accelerates edge chipping and reduces hole quality.
• Coolant Delivery: Use high-pressure internal coolant (min. 70 bar) for optimal chip evacuation in 5×D applications. Ensure coolant concentration is 8–10% for water-miscible fluids.
• Peck Cycle: For depths exceeding 3×D, implement a peck cycle with retract to clear chips. Peck depth should not exceed 60% of flute length.
• Entry Angle: When drilling into angled surfaces, use a spot drill or center drill to create a 90° entry surface. Alternatively, reduce feed to 50% for the first 1×D.
• Exit Strategy: Reduce feed by 30% in the last 2 mm before breakthrough to minimize burr formation and exit chipping.
• Tool Life Monitoring: Monitor flank wear (VB). Recommended regrind limit is VB = 0.3 mm. Do not exceed this to prevent catastrophic failure.
• Storage: Store in original packaging in a dry environment. Avoid contact between cutting edges to prevent micro-chipping.
