Product Overview

The Kyocera #52 PR1215 SGS56261 is a premium solid carbide drill engineered for general engineering drilling. Manufactured in Japan to exacting OEM standards, this tool features fine grain carbide with a PVD TiSiN coating, delivering exceptional performance across demanding production environments. The tapered geometry ensures stable chip evacuation and minimal deflection, even in deep-hole applications up to 30.0×D.

ISO Designation Breakdown

Grade Details – Key Grade Characteristics

PR1215 is a fine grain carbide grade featuring a PVD TiSiN multi-layer coating. The coating exhibits a distinctive Silver-blue appearance and provides superior thermal stability and oxidation resistance.

Property	Value	Performance Impact
Hardness	92.8 HRA	Excellent wear resistance in continuous cutting
Transverse Rupture Strength	3,300 MPa	High chipping resistance under intermittent loads
Coating Thickness	2.0 µm	Balanced protection without edge rounding
Max Operating Temp	1000 °C	Suitable for dry and high-speed machining
Friction Coefficient	0.20	Reduced built-up edge and adhesion

Grade Comparison Matrix

Grade	Best For	Speed (v_c)	Feed (f_n)
PR1215	Titanium machining	45-105 m/min	0.10-0.35 mm/rev
PR1535	General steel, stainless	40-100 m/min	0.05-0.25 mm/rev
CA6535	Cast iron, heavy roughing	60-120 m/min	0.10-0.35 mm/rev
PR1725	Hardened steel, superalloys	30-80 m/min	0.03-0.20 mm/rev
CA115	Mild steel, continuous cut	50-110 m/min	0.08-0.30 mm/rev

Chipbreaker Profile

The TG chipbreaker geometry is optimized for titanium machining. It features a precisely ground rake face with a 8° positive rake angle and a 1.0 mm land width. This configuration promotes tightly curled chips that break predictably, preventing nest formation and protecting the finished hole wall.

Chipbreaker Type: TG-style open groove
Rake Angle: 8° positive
Land Width: 1.0 mm
Chip Curl Radius: 6 mm (typical)
Chip Thickness Ratio: 1:4

Recommended Applications & Workpiece Materials

Material Group	ISO Code	Suitability	Notes
Titanium	P20	★★★★★ Excellent	Primary target material
Stainless Steel	M30	★★★★☆ Very Good	Use reduced speed for austenitic grades
Cast Iron	K20	★★★★☆ Very Good	Excellent for gray and nodular cast iron
Aluminum	N20	★★★☆☆ Good	Polished flute recommended for sticky alloys
Hardened Steel	H20	★★★☆☆ Good	Up to 45 HRC with optimized parameters

Application Map by Operation

Operation	Suitability	Max Depth	Recommended coolant
Through-hole Drilling	✓ Optimal	30×D	External / Through-spindle
Blind-hole Drilling	✓ Optimal	24×D	External with chip evacuation
Peck Drilling	✓ Recommended	36×D	High-pressure through-spindle
Helical Interpolation	✓ Possible	15×D	External flood coolant
Counterboring	△ Caution	1×D	External with reduced feed

Recommended Cutting Conditions

Values are starting recommendations. Adjust based on machine rigidity, workpiece clamping, and coolant delivery.

Material	v_c (m/min)	f_n (mm/rev)	Coolant
Titanium	45-105	0.10-0.35	Emulsion 6-8%
Stainless Steel	36-73	0.08-0.24	Emulsion 8-10% / Oil
Cast Iron	54-115	0.12-0.39	Dry / Compressed air
Aluminum	90-262	0.15-0.70	Emulsion 5-6% / MQL
Hardened Steel	22-42	0.05-0.14	Oil / High-pressure emulsion

Operating Guidelines

Run-in Period: Reduce v_c and f_n by 20% for the first 10 holes to stabilize the cutting edge.
Peck Cycle: For depths >3×D, use a peck depth of 1-1.5×D with full retract to break chips.
Coolant Pressure: Maintain ≥20 bar (290 psi) for through-spindle coolant when drilling >5×D.
Spindle Runout: Ensure TIR <0.01 mm at the tool point to prevent uneven wear.
Tool Life Check: Monitor flank wear (VB). Regrind or replace when VB >0.3 mm for roughing or >0.15 mm for finishing.
Storage: Store in original packaging away from humidity and direct sunlight. Avoid contact with other carbide tools to prevent edge chipping.

Toolholder Compatibility

The 10.00 mm shank is precision ground to h6 tolerance, ensuring secure clamping in standard collets and hydraulic chucks. Verified compatible holders:

Holder Type	Taper	Clamping Method	Max Speed
BT50 Hydraulic Chuck	BT / HSK	Hydraulic expansion	20,000 RPM
ER32 Collet Chuck	BT / SK	Collet clamp	15,000 RPM
