    Button bits are a moderately abrasive type of bit used where fast penetration is required, and straightness is less critical. Ideal for medium to hard ground, these bits are recognized by their characteristic raised buttons and grooved chipways and flushing holes on the face.

    Blade bits are used when a straight hole is critical.
