TiN-Tip Heat Resistance (A002 Series) The Titanium Nitride coating at the point is vital for a 9/16″ bit. The larger the diameter, the higher the surface speed at the outer edges; the TiN coating allows the bit to withstand the resulting friction heat, maintaining its edge up to 3x longer than standard HSS.
118° Split Point Geometry Features a self-centering point that prevents the bit from “skating” or “walking” across the surface. This is especially important for 9/16″ bits, as a wandering bit of this size can cause significant damage to the workpiece.
Steam Tempered (Blue/Black) Body The porous surface treatment is designed to hold cutting lubricants. As you drill deeper, the steam-tempered finish helps “wick” oil down to the cutting face, preventing the metal chips from welding to the flutes.
Maximum Swarf Capacity The flutes are precision-ground to eject the large volume of heavy chips generated by a 14.29mm cut. This efficient evacuation is key to preventing the bit from seizing under load.
Straight Shank Configuration Note: Standard Jobber 9/16″ bits have a full-diameter 9/16″ shank. This will not fit in a standard 1/2″ (13mm) portable drill chuck.
Manufactured to ANSI or DIN 338 standards (depending on the specific series), the 9/16″ bit is a high-torque tool. Because this size exceeds the 1/2″ (12.7mm) threshold, it is a “borderline” bit typically requiring industrial-grade machinery or specialized chucks to operate safely and effectively.
