Chipbreaker Profile

The 3/8 TC drill utilizes a XHF (Extra High Feed) chipbreaker geometry engineered for the nominal diameter range. The flute profile incorporates a variable helix design with polished rake surfaces to minimize friction and promote efficient chip curling and evacuation.

Parameter	Value	Function
Chipbreaker Type	XHF (Extra High Feed)	Optimized chip segmentation for 3/8" diameter
Rake Angle (γ)	8° ± 2°	Balances edge strength with cutting efficiency
Flute Surface Finish	Ra 0.2 μm	Reduces chip adhesion and heat generation
Core Thickness	0.22 × D1	Maximizes rigidity while maintaining coolant flow

Recommended Applications & Workpiece Materials

Carbon & Alloy Steels (≤ 45 HRC): Excellent chip control and surface finish in 1045, 4140, 4340 grades
Stainless Steels: Austenitic (304, 316) and martensitic (410, 420) series with reduced built-up edge tendency
Cast Iron: Gray cast iron (Class 30-40) and ductile iron (65-45-12) with high wear resistance
Titanium Alloys: Ti-6Al-4V at moderate speeds with adequate coolant delivery
High-Temperature Alloys: Inconel 718 and Hastelloy at reduced parameters with rigid setup

Application Map by Operation

Titanium Alloy Ti-6Al-4V	< 350 HB	25-45	0.05-0.10	Wet required

*Dry machining requires stable machine spindle and rigid workholding. Adjust parameters based on machine rigidity and hole depth.

Operating Guidelines

Runout Limit: Maximum tool runout at the cutting edge should not exceed 0.01 mm (0.0004") to prevent uneven wear and premature failure.
Pecking Cycle: For holes deeper than 3×D, implement a peck cycle with retract to clear chips. Peck depth = 1.0×D for <5×D holes, 0.5×D for >5×D holes.
Coolant Pressure: Minimum 70 bar (1,000 psi) through-tool coolant recommended for holes >3×D in stainless and titanium.
Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent chipping on inclined surfaces.
Tool Overhang: Minimize overhang to 4×D or less. Use hydraulic or shrink-fit holders for optimal rigidity.
Speed/Feed Ramp: Reduce feed by 30% for the first 1 mm of entry to stabilize the tool before full engagement.

Toolholder Compatibility

Toolholder Type	Recommended Model Series	Clamping Force	Runout Capability
ER Collet Chuck	ER25, ER32 Collet Chuck	Medium	≤ 0.015 mm @ 3×D
Hydraulic Chuck	HydroForce Mini / Standard	High	≤ 0.005 mm @ 3×D
Shrink-Fit Chuck	ThermoGrip Slim / Heavy Duty	Very High	≤ 0.003 mm @ 3×D
