Counterbore HSS For Screw Size #4

Center Drill Plain #1 is an indispensable tool in the field of hole making, particularly during drilling or tapping tasks that require precise centering before carrying out operations on materials like metals, plastics, or wood with exceptional accuracy demands. It is crafted from high-carbon steel imbuing it with strength, durability to endure abrasion and wear when working within a diameter range of 1/8 to 5/32 on machines capable of accepting its size. Moreover, this product comes with a plain finish that provides for seamless transitions between holes and eliminates the need for constant changes thereby allowing for versatile usage while ensuring top-grade performance during operations across diverse industries like aerospace, automotive or general engineering centered on drilling and holemaking activities.

High-speed steel counterbores are the most common choice for creating a flat-bottomed cavity at the top of the hole so that a bolt, nut, or other part is hidden beneath or sits flush with the top of the hole when installed into it. High-speed steel is less brittle than cobalt and can better withstand vibration and chattering. Sometimes known as solid pilot counterbores, these counterbores have a built-in pilot that cannot be removed and which keeps the counterbore centered in the hole to ensure a level seat.
