OSG

OSG is a Japanese manufacturer of cutting tools, established in 1938 and headquartered in Toyokawa, Aichi Prefecture. The company specializes in taps, drills, end mills, and other precision tooling for metalworking industries. OSG's product line includes thread-forming taps, spiral flute taps, carbide end mills, solid carbide micro drills, and indexable tooling. The micro drill bits supplied by 3G Electric feature solid carbide construction with TiAlN (titanium aluminum nitride) coating, 140° or 130° 4-facet point geometries, and regular spiral flute designs. These drills are available in diameters from 0.44 mm to 3.15 mm, with shank diameters matching the drill diameter for precision collet holding. OSG tools are manufactured to JIS (Japanese Industrial Standards) and ISO specifications, with tolerances typically held to h6 or better for shank diameters. The TiAlN coating provides oxidation resistance up to 800°C and hardness around 3000 HV, suitable for machining hardened steels, stainless steels, and cast irons. 3G Electric stocks over 15,000 OSG SKUs, including micro drills, taps, and end mills, supporting global procurement for maintenance, repair, and production operations. The micro drill series is designed for CNC machining centers and automated drilling applications requiring consistent hole quality in small diameters. OSG's 4-facet point geometry reduces thrust forces and improves centering accuracy compared to conventional split-point designs. The regular spiral flute design provides adequate chip evacuation in shallow hole drilling (depth-to-diameter ratios up to 3:1). For deeper holes, OSG recommends their EX-SUS-GDS series with variable helix geometry. All OSG micro drills supplied by 3G Electric are packaged individually in protective sleeves to prevent edge damage during handling and shipping. The drills are suitable for use with standard ER collet chucks or hydraulic chucks, with recommended cutting speeds ranging from 30 to 80 m/min depending on workpiece material. 3G Electric provides technical datasheets and application support for OSG tool selection, including speed and feed recommendations based on material hardness and machine rigidity.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang OSG dari 3G Electric.

What point geometry is standard on OSG micro drill bits supplied by 3G Electric?

The OSG micro drill bits in the 3G Electric catalog feature a 140° 4-facet point geometry, except for SKU 34XV50 which has a 130° 4-facet point. The 4-facet design provides self-centering capability and reduces walking on entry, which is critical for small-diameter drilling. The 140° point is suitable for general-purpose drilling in steels and stainless steels, while the 130° point on the 3.15 mm drill is optimized for harder materials or when increased edge strength is required.

What coating is applied to OSG micro drill bits and what are its benefits?

OSG micro drill bits are coated with TiAlN (titanium aluminum nitride). This coating offers oxidation resistance up to 800°C and a hardness of approximately 3000 HV. It reduces friction and heat generation during cutting, allowing higher cutting speeds and longer tool life compared to uncoated carbide. TiAlN is effective on materials such as alloy steels, stainless steels, and cast irons. The coating thickness is typically 2-4 microns, which does not significantly alter the drill diameter tolerance.

What shank diameter do OSG micro drill bits have?

OSG micro drill bits have a shank diameter equal to the drill diameter. For example, a 1.6 mm drill has a 1.6 mm shank. This is standard for micro drills to maintain concentricity and allow use with precision collets. The shank tolerance is typically h6, ensuring consistent clamping force and runout control. 3G Electric stocks drills with shank diameters from 0.44 mm to 3.15 mm, all with matching shank-to-drill diameter ratios.

What flute design do OSG micro drill bits use?

OSG micro drill bits feature a regular spiral flute design. This geometry provides balanced chip evacuation and cutting edge strength for general-purpose drilling in shallow holes (depth-to-diameter ratios up to 3:1). The regular spiral is suitable for most ferrous and non-ferrous materials. For deeper holes or stringy materials, OSG offers variable helix or high-helix designs in other product series, but the micro drills in the 3G Electric catalog are all regular spiral.

What materials can OSG micro drill bits machine?

OSG micro drill bits with TiAlN coating are designed for machining hardened steels (up to HRC 50), stainless steels, alloy steels, cast irons, and titanium alloys. The carbide substrate provides wear resistance, while the coating handles thermal loads. They are not recommended for aluminum or copper alloys due to built-up edge risks; for those materials, uncoated or DLC-coated drills are preferred. 3G Electric can advise on alternative OSG series for non-ferrous applications.

Does 3G Electric supply OSG products?

Yes — 3G Electric (S) Pte. Ltd. supplies OSG products. We stock the OSG catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
