■ Micro Drill: MDUS ø0.03 to ø0.19 mm ● High-precision shank (Shank tolerance h3, circularity 0.3μm or less, cylindricity 0.5μm or less) ● New ultra-thin TiAlN coating gives improved wear resistance ● Perfect for drilling steel, stainless steel, or copper ● Available from ø 0.03 mm to ø0.19 mm in 0.005 mm increments
For Steel, Stainless Steel and Other Metals
■ Application Examples

Part Material : MDUS 0030-30C ( ø0.03 mm) Cutting Conditions : n = 15,000 RPM, v f = 0.118” IPM Step Feed = 0.0001” ø30μm : 304 Stainless Steel Tool
Part Material
: 316 Stainless Steel
Tool : MDUS 0100-30C ( ø0.04” ) Cutting Conditions : n = 20,000 RPM, v f = 0.787 IPM Step Feed = 0.0004”
■ Solid Carbide MINI Drill: MDSS ø0.20 to ø1.00 mm ● The combination of a hard, tough carbide substrate and a high-rigidity design (web thickness, flute width ratio, helix angle) greatly improves fracture resistance ● PVD coating designed for small drills significantly extends tool life ● Can be used for a wide range of work materials including carbon steel, alloy steel, die steel, and stainless steel ● Shanks standardised to ø3mm diameter and overall length of 38mm for greater ease of use

MDSS Recommended Cutting Conditions (Wet) <Inquire about cutting conditions for the MDUS type>
1. The conditions on the left are recommended under wet conditions, using water-soluble coolant. 2. If cutting noise and vibration are present, please adjust the cutting conditions accordingly. 3. If the machine cannot achieve the standard spindle speed, please use the maximum spindle speed available. In this case, lower the feed rate by the same ratio. * Step feed is recommended for drilling of holes deeper than 3xD (D=drill diameter).
