Product Overview
The Kyocera SGM09156 (KSPT EDP 09156) is a Series M4 micro end mill from KYOCERA SGS Precision Tools — a solid, sub-micron grain carbide, 4-flute, 30° helix, corner-radius cutter with a 0.055" cutting diameter, 0.015" corner radius and standard 1.5xD flute length. The four-flute design raises feed-per-rev and delivers the finest floor and wall finishes in the micro line. Finished with KSPT's proprietary Ti-Namite-A (AlTiN) PVD coating for superior chip flow and wear resistance.
The 1.5xD flute length is the rigid, general-purpose configuration — the first choice for micro slotting, profiling and engraving where maximum stiffness matters. With a reinforced 0.015" corner radius for maximum corner strength, longer edge life and heavier finishing passes, the SGM09156 produces crisp detail, low burr formation and mirror-quality finishes in tool steels, stainless steels, cast iron, aluminum and copper alloys, titanium and high-temperature alloys — a proven choice for micro molds, medical components, electronics housings, watchmaking and fine engraving work.

Grade Details - Key Grade Characteristics
This tool pairs KSPT's application-specific sub-micron grain carbide substrate with the proprietary Ti-Namite-A (AlTiN) PVD coating — the wear-resistant option in the M3CR family. Key grade characteristics:
| Characteristic | Engineering Benefit |
|---|---|
| Ti-Namite-A (AlTiN) coating | Aluminum-titanium-nitride PVD layer engineered for abrasive wear resistance in steels, cast irons and super alloys |
| Superior chip flow | KSPT's proprietary coating promotes smooth chip evacuation, driving productivity even at low spindle speeds |
| Thermal barrier | AlTiN forms a protective aluminum-oxide surface in the cut, shielding the edge at elevated temperatures |
| Sub-micron carbide substrate | Ultra-fine grain core resists micro-chipping at micro diameters |
| Extended tool life | Coating + micro-tool substrate significantly outlast uncoated edges in ferrous and high-temp materials |
| ISO 9001:2015 manufacture | Every tool produced under KSPT ISO-certified quality procedures for lot-to-lot consistency |
Grade Comparison Matrix
The M4CR geometry is stocked in two material options. This listing is the Ti-Namite-A (AlTiN) coated version (EDP 09156); the uncoated version is orderable as EDP 09016.
| Parameter | This Tool — Ti-Namite-A, AlTiN (EDP 09156) | Alternate — Uncoated (EDP 09016) |
|---|---|---|
| Coating | Ti-Namite-A aluminum-titanium-nitride PVD | None (bright, polished carbide) |
| Substrate | Sub-micron grain carbide (micro-tool grade) | Sub-micron grain carbide (micro-tool grade) |
| Edge condition | Coating-honed for maximum wear resistance | Sharpest possible edge; finest finishes |
| Heat management | AlTiN thermal barrier for hotter, drier cuts in steels | Relies on coolant / air blast; excels at moderate temperatures |
| First-choice materials | Carbon / alloy / tool steels, cast iron, titanium, high-temp alloys | Aluminum, copper, brass, plastics, fine finishing |
| Chip flow | Superior — proprietary coating drives chip evacuation even at low spindle speeds | Very good on polished flutes |
| Choose this option when | Abrasive wear, heat and tool life in ferrous / high-temp materials are the priority | Ultimate edge sharpness in non-ferrous materials is the priority |
Chipbreaker Profile
Solid carbide end mills do not use a molded chipbreaker; instead, chip control on the SGM09156 is engineered directly into the flute and face geometry:
| Geometry Element | Chip-Control Function |
|---|---|
| 4-flute geometry | More teeth per revolution for finer finish and higher table feed; best chip control in light-engagement finishing |
| 30° helical flutes | Shears chips away from the cut and augers them up and out of the pocket, reducing re-cutting |
| Ti-Namite-A coated flutes | Low-friction, wear-resistant surface — chips evacuate smoothly and the coating resists chip abrasion |
| Positive rake face | Produces small, manageable chips at micro feed-per-tooth values and lowers cutting pressure |
| Corner-radius edge prep | Controls chip thickness at the corner, the most highly stressed point of the edge |
Application note: four flutes leave less chip space than three — in full-width slots keep Ap at or below the tabulated limit, evacuate chips with a directed air blast or coolant, and mill deep slots in steps. The catalog feed values in this listing already include chip-thinning adjustment where applicable.

Recommended Cutting Conditions
KSPT baseline parameters for the 0.055" diameter, standard 1.5xD flute length (feeds include the ×1.57 4-flute multiplier for this flute length). rpm = Vc × 3.82 ÷ DC; ipm = baseline feed × multiplier. Fz shown for the nearest chart reference diameter (0.0625").
Reduce speed and feed for harder materials. If recommended rpm exceeds machine capability, use maximum available rpm and recalculate feed.

Operating Guidelines
| Topic | Recommendation |
|---|---|
| Tool runout | Hold total indicated runout (TIR) to ≤ 0.0002" at the tool — runout is the #1 cause of premature micro-tool failure |
| Toolholding | Use precision collet, shrink-fit or hydraulic micro chucks; never side-lock or set-screw holders |
| Gauge length | Clamp maximum shank length; keep stick-out to the minimum that clears the workpiece and fixture |
| Milling strategy | Climb mill whenever possible; program arc-lead entries and avoid sharp direction reversals at full engagement |
| Entry moves | Helical ramp at ≤ 1° using slotting parameters; straight plunging is not recommended with the 0.055" end |
| Coolant / chip clearing | Flood coolant for steels, stainless, titanium and super alloys; directed air blast for aluminum, plastics and deep slots |
| Finishing | Reserve a finishing allowance of ≤ 0.02 × DC (0.0011") radially and reduce feed ~30% for mirror results |
| Chip evacuation | With 4 flutes, clear chips every pass in slots — compressed chips are the main cause of corner breakage |
| Tool life monitoring | Inspect the edge under ≥ 20× magnification; replace at the first sign of micro-chipping or corner wear |
| Break-in | Run the first 5–10 minutes at ~70% of table feed to condition the edge, then ramp to full parameters |
Toolholder Compatibility
The 1/8" (3.175 mm) h6 cylindrical shank fits all standard micro-tool holding systems:
| Holder Type | Specification | Suitability / Notes |
|---|---|---|
| ER collet chuck | ER11 or ER16 with 1/8" (3.175 mm) precision collet | ●●● Excellent — most common choice; verify TIR after assembly |
| Shrink-fit holder | 3.175 mm micro shrink-fit bore | ●●● Excellent — best runout and balance for high rpm |
| Hydraulic micro chuck | 3.175 mm bore, radial clamping | ●●● Excellent — vibration damping for fine finishes |
| High-speed spindle | 24,000–60,000 rpm recommended | Required to reach catalog Vc in non-ferrous materials; else use max rpm and recalculate feed |
| Milling chuck / side lock | Set-screw type holders | ✕ Not recommended — damages shank and induces runout |
| Balance quality | G2.5 or better at operating rpm | Critical above 20,000 rpm with micro tools |
