OSG
Frequently asked questions
Common questions about OSG from 3G Electric.
What is the difference between OSG spiral-point and spiral-flute taps?
OSG spiral-point taps, such as the M16x2 model with 6H tolerance, are designed for through-hole threading. The spiral point pushes chips ahead of the tap, preventing chip accumulation in the hole. Spiral-flute taps, like the M5x0.8 with bottoming chamfer, have flutes that pull chips backward out of the hole, making them suitable for blind holes. The choice depends on hole type and chip evacuation requirements. Both styles are available in various materials and coatings.
What materials are OSG thread-forming taps suitable for?
OSG thread-forming taps, such as the M8x1.25 with D9 / 6H tolerance, are intended for ductile materials including aluminum, steel, and stainless steel. These taps form threads by displacing material rather than cutting, which can produce stronger threads and eliminate chips. They are typically used in applications where chip-free threading is required. The cobalt construction and TiN coating provide wear resistance. They are not recommended for brittle materials where displacement could cause cracking.
What are the specifications of the OSG A BRAND extra long drill bit?
The OSG A BRAND extra long drill bit is a coolant-through solid carbide drill with a 2 mm diameter and 75 mm overall length. It features a 140° X-thinning point and is designed for steel and cast iron. The coolant-through design helps with chip evacuation and heat reduction in deep-hole drilling. The extended length allows access to difficult-to-reach areas. This drill is part of OSG's range of solid carbide drilling tools.
What is the purpose of an OSG STI tap?
OSG STI taps are used to cut internal threads that will accept helical wire thread inserts. The #10-24 UNC STI tap with H2 tolerance and plug chamfer is an example. These taps produce a larger minor diameter than standard taps to accommodate the insert. The 2B-3B class of fit indicates the tolerance range for the thread. STI taps are common in aerospace, automotive, and industrial repair applications where thread reinforcement is needed.
What are OSG straight-flute solid carbide chucking reamers used for?
OSG straight-flute solid carbide chucking reamers are used for precision finishing of drilled or bored holes. They achieve tight diameter tolerances and smooth surface finishes in ferrous and non-ferrous materials. The straight-flute design is suited for through-hole reaming where chip evacuation is not a primary concern. These reamers are available in various diameters, such as 0.2441 in and 0.4291 in, with specific manufacturer part numbers. They are typically used in machining operations requiring accurate hole sizing.
