Key Features

• Premium Hi-Molybdenum HSS Construction: Manufactured from high-grade Molybdenum High-Speed Steel (HSS) with a high Vanadium content, ensuring exceptional hardness and longevity, even when drilling challenging materials like stainless steel and titanium alloy. The body and clearance surface are treated for maximum lubricity and the "space-age Nitro-Carbonized steel" withstands higher drilling temperatures while maintaining sharpness.
• Silver & Deming (S&D) 1/2" Reduced Shank: Features a 1/2-inch reduced shank with three precision-ground flats to prevent slippage and ensure a secure grip in standard drill chucks, accommodating larger drill diameters with common equipment.
• 135° Split Point Tip: Designed with a 135-degree split point that allows for fast penetration and accurate starting without the need for a pilot hole or center punch, effectively eliminating bit "walking."
• Precision Ground: Every aspect, including the point, flutes, body clearance, and drill diameter, is precision ground to exact tolerances, ensuring ultimate accuracy and smooth chip evacuation for consistent performance.
• Made in the USA: KnKut products are proudly manufactured in the United States, adhering to stringent quality and performance standards.

Applications

This 9/16" S&D drill bit is well-suited for a variety of medium to heavy-duty drilling tasks. It excels in metalworking for fabrication, machine shops, and industrial settings where drilling through hard steel, work-hardened stainless steel, titanium alloy, and other robust metals is common. In automotive and manufacturing, it is ideal for creating accurate, oversized holes for bolts, rivets, or other hardware during repairs, maintenance, and custom machinery work. Its compatibility with standard 1/2" drill chucks makes it versatile for use in hand-held drills, drill presses, and other professional drilling equipment.
