Product Overview

The Kyocera #3 DRILL 2FL 5XD TN SGS51429 is a premium solid-carbide twist drill engineered for high-performance CNC machining. Featuring a 5.41 mm (0.2130") diameter with a 2-flute design and 5×D flute length, this tool delivers exceptional hole quality, dimensional accuracy, and extended tool life in demanding production environments.

ISO Designation Breakdown

Designator	Meaning
#3	Tool diameter / size identifier (0.2130" / 5.41 mm)
DRILL	Primary tool family — solid carbide drill
2FL	2-flute geometry for balanced chip evacuation
5XD	Flute length = 5 × diameter (27.1 mm)
TN	Grade — TiAlN-coated micro-grain carbide for universal application
SGS51429	Manufacturer part number (MPN)

Engineering Dimensions & Geometry

Parameter	Value	Tolerance
Cutting Diameter (D)	5.41 mm / 0.2130"	h5

Grade Comparison Matrix

Grade	Wear Resistance	Toughness	Heat Resistance	Best For
TN	★★★★☆	★★★★☆	★★★★★	Universal steel, stainless, cast iron
PV	★★★★★	★★★☆☆	★★★★☆	Hardened steels > 50 HRC
CA	★★★☆☆	★★★★★	★★★☆☆	Interrupted cuts, roughing
GW	★★★★☆	★★★★☆	★★★★☆	Aluminum & non-ferrous alloys

Chipbreaker Profile

The #3 features Kyocera's proprietary SGS (Special Groove System) chipbreaker geometry optimized for 2-flute drills. The polished flute surface (Ra 0.2 μm) minimizes built-up edge, while the widened flute gullet provides efficient chip evacuation for 5.41 mm diameter holes up to 5×D depth.

Polished rake face reduces cutting forces by ~15% compared to standard ground drills
Enhanced chip curling radius prevents chip packing in deep-hole applications
Stable chip formation across feed rates of 0.10–0.25 mm/rev

Recommended Applications & Workpiece Materials

Material Group	Examples	Machinability
Carbon Steel	C45, C60, 1045, 1060	Excellent
Alloy Steel	4140, 4340, 42CrMo4	Excellent
Stainless Steel	304, 316, 17-4PH	Very Good
Cast Iron	GG25, GGG40, Class 40	Good
Tool Steel	H13, D2, O1 (pre-hardened < 45 HRC)	Good
Titanium Alloy	Ti-6Al-4V (limited speed)	Moderate

Application Map by Operation

Operation	Suitability	Notes
Through-hole Drilling	★★★★★	Primary application; optimized for full breakthrough
Blind-hole Drilling	★★★★☆	Use peck cycle for depths > 3×D
Cross-hole Drilling	★★★☆☆	Reduce feed to 70% at intersection
Stack Drilling	★★★★☆	Ensure rigid clamping; use coolant
Enlarging / Reaming	★★☆☆☆	Not recommended; use dedicated reamer

Recommended Cutting Conditions

Material	Cutting Speed (Vc) m/min	Feed (f) mm/rev	RPM (approx.)
Mild Steel (< 300 HB)	80–120	0.12–0.20	6,469
Alloy Steel (300–400 HB)	60–90	0.10–0.16	4,805
Stainless Steel (AISI 304)	50–70	0.10–0.14	3,696
Cast Iron (GG25)	90–130	0.14–0.22	7,024
Tool Steel (40–45 HRC)	40–60	0.08–0.12	3,142

Conditions based on high-pressure internal coolant supply (70 bar min) and stable toolholder setup. Adjust by ±15% for dry machining.

Operating Guidelines

Coolant: High-pressure internal coolant (70–150 bar) strongly recommended for 5×D drilling to ensure chip evacuation and heat dissipation.
Peck Cycle: For blind holes > 3×D, use peck depth of 1.0–1.5×D with full retract to break chips.
Tool Overhang: Minimize overhang to < 4×D for best rigidity. Use hydraulic or shrink-fit holders for critical applications.
Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk-off on angled surfaces.
Speed/Feed Ramp: Reduce feed by 50% for the first 1 mm of engagement, then ramp to full feed over 0.5 mm.
Re-sharpening: Not recommended; solid carbide design is intended for full tool life consumption. Inspect for flank wear > 0.3 mm as replacement criterion.

Toolholder Compatibility

Holder Type	Compatibility	Recommendation
Hydraulic Chuck (Hydro)	★★★★★	Best damping; ideal for 5×D applications
Shrink Fit	★★★★★	Maximum rigidity and runout control (< 3 μm)
ER Collet (ER16–ER25)	★★★★☆	Acceptable for through-holes; ensure collet quality
Milling Chuck	★★★☆☆	Use only for short holes (< 2×D)
Drill Chuck (Keyless)	★★☆☆☆	Not recommended for precision CNC work
