Product Overview

The Kyocera 25/64 DRILL 2FL SGS51125 is a premium solid-carbide twist drill engineered for high-precision CNC machining. With a diameter of 0.3906" (9.92 mm), this two-flute design optimizes chip evacuation and hole accuracy in demanding production environments. The KPD001 substrate combines micro-grain carbide with an advanced AlTiN coating for exceptional wear resistance and thermal stability during continuous high-speed drilling operations.

Chipbreaker Profile

The 25/64 SGS51125 features a precision-ground parabolic flute profile with a 135° split-point geometry. The web-thinning design reduces thrust forces by approximately 25% compared to conventional chisel-edge drills, enabling self-centering entry without a pilot hole in most materials. The flute gullet is optimized for 9.92 mm diameter, providing a chip-space ratio of 1.8:1 for reliable chip evacuation at depths up to 3×D.

Point Geometry: Split-point with honed edge (T-land 0.05 mm)
Flute Form: Parabolic helix with polished surface (Ra 0.2 μm)
Margin Width: 0.08 mm per side for stable wall contact
Back Taper: 0.01 mm over flute length to reduce friction

Recommended Cutting Conditions

Parameters optimized for 25/64 (9.92 mm) diameter. Adjust based on machine rigidity and coolant delivery.

Workpiece Material	Cutting Speed Vc	Feed fn	RPM (approx.)	Coolant
Carbon Steel	40-60 m/min	0.198 mm/rev	1,604	Emulsion 8-10%
Alloy Steel	35-50 m/min	0.178 mm/rev	1,403	Emulsion 10-12%
Stainless Steel	25-40 m/min	0.165 mm/rev	1,123	Emulsion 12-15%
Gray Cast Iron	50-70 m/min	0.218 mm/rev	1,924	Compressed Air / Mist
Aluminum	80-120 m/min	0.298 mm/rev	2,567	Kerosene / Water-Soluble

Operating Guidelines

Entry Angle: Ensure perpendicular entry (< 0.5° deviation) to prevent corner chipping. Use a spot drill for inclined surfaces > 5°.
Peck Cycle: For depths > 1.5×D, use peck depth of 0.5×D with full retract to break chips. For stainless steel, reduce peck depth to 0.3×D.
Coolant Pressure: Maintain minimum 20 bar (290 psi) for through-tool coolant. For external flood coolant, direct nozzle at tool point.
Ramp-In: Use 50% feed rate for the first 0.5 mm to stabilize entry, then ramp to 100% over the next 1.0 mm.
Tool Life Monitoring: Expected tool life is 15-25 minutes in steel at recommended parameters. Monitor flank wear; regrind at VB = 0.15 mm.
Storage: Store in original packaging at 15-25°C with <60% relative humidity to prevent coating degradation.

Toolholder Compatibility

Holder Type	Min. Clamping Diameter	Max. Runout	Recommendation
ER Collet Chuck	ER16 / ER20	< 0.01 mm	Good for general use
Hydraulic Chuck	Hydro 6 mm / 1/4"	< 0.005 mm	Best for precision
Shrink Fit	9.92 mm	< 0.003 mm	Excellent for high speed
