7 Buttons 11 Degree Tapered Drill Button Bit Rock 38mm

7 Buttons 11 Degree Rock Button Bits 38mm Tapered Button Bit

Description:

Cemented carbide is one of the most successful composite engineering materials produced.

Its unique combination of strength,hardness and toughness satisfies the most demanding applications – but working with such high stresses, inserts and buttons are more subject to wear.

MTH also use the same hot inserting technology as including the steel materials and Heat treatment.

Button bits should be reground when penetrati on rat es drop or if the cemented carbide shows signs of damage

Fixed grinding routines often result in good working practices.

Bits for instance, can be examined and then reground after a specific number of holes, or at the end of the shift. Premature grinding is not necessarily uneconomical since less carbide needs to be ground off. It is better to regrind rather than reducing productivity due to damage.

Correct grinding adds considerably to drill bit service life. But equally important, it also enhances the performance of the entire drilling operation, especially hole straightness.
