2-Flute Solid Carbide Micro Drill Overview
This 2-flute solid carbide micro drill is designed for precision small-hole machining in selected stainless-steel grades. The confirmed standard range covers Ø0.20–1.00 mm cutting diameters with a 3 mm fixed cylindrical shank. Fine-grain carbide, precision-ground cutting geometry and diameter-specific flute lengths support rigidity, controlled entry and chip evacuation in micro drilling. The series can be used for blind holes, through holes and functional passages on precision CNC lathes, Swiss-type lathes, machining centers and micro-drilling machines under low-runout, short-overhang and stable coolant conditions.

Product & Cutting-Edge Details
Tool Nomenclature & Dimensions
Reference dimensions and configuration for this 2-flute solid carbide micro drill for stainless steel. The confirmed standard series covers Ø0.20–1.00 mm cutting diameters with a fixed 3 mm cylindrical shank. Flute length is matched to cutting diameter to maintain practical reach and rigidity in micro-hole machining.
Standard Size Range
The confirmed product series uses a fixed 3 mm shank with diameter-specific flute lengths. The table below summarizes the validated standard range without replacing the detailed production size chart.
Stainless-Steel Micro-Drilling Guidance
- Control Runout: Use a clean precision holder matched to the 3 mm shank and verify runout close to the cutting section.
- Keep Overhang Short: Use only the flute length and tool reach required for the actual hole depth.
- Maintain Continuous Feed: Avoid unnecessary dwell that can increase rubbing and promote stainless-steel work hardening.
- Support Chip Evacuation: Direct coolant or mist toward the cutting zone and monitor chip packing, especially in blind or relatively deep micro holes.
Recommended Starting Cutting Parameters
Starting cutting conditions should be adjusted according to micro-drill diameter, stainless-steel grade, hardness, hole depth, tool overhang, spindle runout and coolant delivery. Use the general carbide-drill data as a reference rather than as fixed values for every micro-drilling application.

Product FAQs
Product-specific information about stainless-steel micro drilling, available sizes, coolant requirements, coating options and custom configurations for this 2-flute solid carbide micro drill.
What stainless-steel materials is this micro drill designed for?
This drill is intended for precision small-hole machining in stainless-steel components. Common austenitic, martensitic and precipitation-hardening stainless grades can be reviewed according to the exact material grade, hardness, hole diameter and machining conditions. Final cutting parameters should be confirmed for the actual application.
Why is a 2-flute geometry used for stainless-steel micro drilling?
A 2-flute configuration provides a practical balance between cutting-edge support and chip evacuation for small-diameter drilling. For stainless steel, maintaining controlled chip removal is especially important because long chips, adhesion and work hardening can increase cutting load in micro-hole applications.
What diameters and length configurations are available?
Standard micro-drill sizes and custom non-standard dimensions can be supplied. Cutting diameter, flute length, overall length and shank dimensions can be reviewed according to the required hole size, drilling depth, machine setup and customer drawing.
Is coolant recommended when drilling stainless steel with a micro drill?
Yes. Stable cooling and lubrication are generally recommended for stainless-steel micro drilling to help control heat, reduce material adhesion and support chip evacuation. The appropriate coolant method depends on hole depth, drill diameter, machine configuration and whether external or through-coolant delivery is available.
Can the point geometry and coating be customized for different stainless-steel grades?
Yes. Point geometry, edge preparation, flute design and coating can be reviewed according to the stainless-steel grade, hardness, hole depth and required tool life. Application-specific PVD coatings or uncoated configurations can be selected after confirming the machining conditions.
What information is required for a quotation?
Please provide the required cutting diameter, hole depth, flute length, workpiece material grade, hardness, coolant condition and estimated quantity. For non-standard micro drills, a drawing or dimensional sketch is recommended so the geometry and tolerances can be confirmed before quotation.
Ordering & OEM FAQs
General information for trial orders, mixed-size purchasing, private labeling and production scheduling.
Do you accept small trial orders?
Yes. Small trial orders are available for application testing, distributor evaluation and customer approval before larger-volume purchasing.
Can mixed sizes be ordered together?
Yes. Different micro-drill diameters and length configurations can normally be combined in one order when the production and coating requirements are compatible. Mixed-size orders are suitable for distributors and multi-size application testing.
Is OEM laser marking available?
Yes. Custom laser marking for logos, model numbers, size identification and batch information can be reviewed together with private labels and OEM packaging requirements.
What is the typical production lead time?
Lead time depends on the diameter, length, coating, quantity and whether the drill is a standard or custom configuration. The production schedule is confirmed after the specifications and order requirements are finalized.
