Description
Do not drill with a cutting-tap drill size: a form tap needs a larger pilot hole, and the wrong size causes tap breakage or poor thread.
OSG New Roll Form Tap (V-Coated), Blind Hole
A thread forming (roll form) tap that creates internal threads by cold forming rather than cutting, used on ductile materials. Common on CNC machining centers and tapping machines for strong, chip-free threads.
Key Features
- Forms the thread by displacing metal, so it makes no chips.
- Needs a larger pre-drilled hole than a cutting tap; use the form-tap drill size.
- Suits blind and through holes; check the hole type listed for the variant.
- Use cutting oil or a suitable lubricant; forming needs more lubrication than cutting.
