OSG Micro Drill Bit: 1.85 mm, 140° 4-Facet Point

The OSG Micro Drill Bit 1.85 mm is used for precision drilling in hardened steels, stainless steels, and other tough materials. Its 140° 4-facet point reduces thrust and walking, while the TiAlN coating extends tool life in high-temperature applications. Common in mold, die, and aerospace manufacturing.

The OSG Micro Drill Bit 3300185 has a 1.85 mm diameter, 140° 4-facet point, TiAlN-coated solid carbide construction, and regular spiral flute design. It is designed for micro-drilling applications requiring high positional accuracy and chip evacuation. The part number is 3300185.

Select the OSG micro drill bit based on material hardness, hole depth, and required tolerance. The 1.85 mm TiAlN-coated bit suits steels and alloys; the 140° point reduces burr formation. For softer materials, consider uncoated or HSS alternatives. Always match flute design (regular spiral) to chip evacuation needs.
