Bright finish improves chip flow in soft or non-ferrous materials
• Bright finish improves chip flow in soft or non-ferrous materials
• For through hole applications
• High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and non-ferrous material
• It increases chip flow in softer materials such as aluminum, wood and plastic
• Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes
• Spiral point taps are used for tapping through holes
• They have a flute geometry that shoots chips ahead of the cutting action to reduce loading and clogging within the flute
• 2.5 x d average tapping depth
• No coolant channel
