Product Overview

The Kyocera 3/8 DRILL 2FL TC SGS58461 is a premium solid carbide twist drill engineered for high-performance holemaking in CNC machining centers. Featuring a 2-flute design with a 140° point angle and 30° helix angle, this tool delivers exceptional chip evacuation, superior hole quality, and extended tool life in demanding production environments. The ultra-fine grain carbide substrate combined with an advanced PVD coating ensures stable performance across a broad spectrum of workpiece materials.

Chipbreaker Profile

The SGS58 series employs a precision-ground helical flute geometry with an optimized chipbreaker land width of 1.43 mm. The flute profile features a 2.38 mm rake face and a controlled clearance angle of 8°–10°, promoting efficient chip curling and evacuation. This design minimizes built-up edge (BUE) in ductile materials and reduces cutting forces by up to 15% compared to standard geometries, ensuring stable drilling depth-to-diameter ratios of up to 5×D in steels and 8×D in aluminum alloys.

Application Map by Operation

Operation	Suitability	Max Depth	Hole Quality
Through-hole drilling	★★★★★	3×D – 5×D	IT8–IT9, Ra 0.8–1.6 μm
Blind-hole drilling	★★★★☆	2×D – 4×D	IT9–IT10, Ra 1.6–3.2 μm

Recommended Cutting Conditions

Workpiece Material	Cutting Speed (Vc)	Feed per Rev (fn)	Coolant
Carbon Steel (C45)	55-90 m/min	0.12-0.25 mm/rev	Internal / External
Stainless Steel (304)	40-60 m/min	0.12-0.25 mm/rev	High-pressure internal
Aluminum Alloy (6061)	150-200 m/min	0.12-0.25 mm/rev	Mist / Air blast
Cast Iron (GG25)	55-90 m/min	0.12-0.25 mm/rev	Dry / Compressed air
Titanium (Ti-6Al-4V)	20–35 m/min	0.12-0.25 mm/rev	High-pressure internal

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece setup, and coolant delivery. Reduce Vc by 20% for depth-to-diameter ratios > 3×D.

Operating Guidelines

Run-out check: Ensure spindle run-out is < 0.01 mm at the tool tip to prevent premature corner chipping.
Peck cycle: For depths > 3×D, use a peck depth of 1×D–1.5×D with full retract to clear chips.
Coolant pressure: Maintain minimum 20 bar (290 psi) internal coolant pressure for holes > 2×D.
Entry angle: Use a 90° entry or chamfer the hole entrance to avoid drill walk on inclined surfaces.
Speed ramp: Gradually ramp spindle speed over 3–5 seconds to avoid thermal shock to the carbide.
Tool change: Inspect flank wear (VB) after every 50 holes; regrind or replace when VB > 0.2 mm.
Storage: Store in original packaging at < 40% humidity to protect coating integrity.

Toolholder Compatibility

Holder Type	Shank Ø	Clamping	Run-out
Hydraulic chuck (HP)	10.0 mm	Hydraulic clamping	≤ 0.003 mm
Shrink-fit holder (HSK-A63)	10.0 mm	Thermal shrink	≤ 0.003 mm
