ShearTap™ Spiral Flute Tap, Oversized, Series: 2091G, Measurement System: Imperial, 3/8-16, UNC, Semi-Bottoming Chamfer, 3 Flutes, HSS, TiN Coated, Class of Fit: H11, Right Hand Cutting, 0.55 in Thread Length, 2.94 in Overall Length
- Features
| TiN coating increases hardness and lubricity for improved thread quality, higher speeds and longer tool life |
| Primarily designed for tapping through holes |
| The spiral flutes draw the chips out of the hole |
| CNC reduced neck design |
| Oversize taps are mainly used for parts that will be plated or heat treated after tapping |
| Also used in materials that tend to shrink after tapping |
| Semi-bottoming style (2-3 thread chamfer) allows threading close to the bottom of blind holes but cuts more efficiently than standard bottoming taps due to a slightly longer chamfer which distributes the cutting load over a greater number of teeth |
