KnKut 29KK7 Stubby Length Drill Bit Set 1/16-1/2 29 Pc

The KnKut 29KK7 Stubby Length Drill Bit Set offers a robust 29-piece collection specifically designed for professional technicians and mechanics. Crafted from premium Hi-Molybdenum tool steel, this set provides durable and precise drilling solutions for demanding automotive and industrial applications. Its specialized construction ensures superior performance in challenging materials, yielding cleaner, rounder, and more accurate holes.

Key Features

• Premium Hi-Molybdenum Tool Steel: Manufactured with high-grade Hi-Molybdenum high-speed steel and high vanadium content, these bits deliver superior hardness and heat resistance, extending bit life in tough materials.
• Gold Surface Treatment with Salt Nitride: The gold surface treatment reduces friction and promotes cooler drilling, enhancing penetration speed and chip evacuation. A salt nitride treatment further improves surface hardness and longevity for demanding use.
• 135-Degree Split Point: This precision tip enables immediate and accurate hole starting without walking, eliminating the need for a center punch or pilot hole and increasing operational efficiency.
• Heavy-Duty Stubby Length Construction: The shorter flute and overall length enhance rigidity and strength, significantly minimizing breakage and deflection when working with high-tensile alloys and work-hardening grades of stainless steel.
• Comprehensive 29-Piece Set: This versatile set includes a full range of fractional sizes from 1/16" through 1/2" by 64ths, providing a wide array of options for diverse professional drilling tasks.
• Three-Flat Shank Design: Sizes 3/16" and above feature a three-flat shank, which improves grip and reduces slippage in drill chucks, ensuring secure operation.

Applications

This KnKut Stubby Length Drill Bit Set is an essential tool for professionals requiring reliable performance in hard-to-drill materials. It is particularly effective for automotive repair, industrial fabrication, and maintenance operations involving materials such as work-hardening grades of stainless steel, cast iron, high-tensile steel, and titanium alloy. The design supports cleaner, rounder, and more accurate holes, critical for precision-dependent component work. These bits are also ideal for use in right-angle drills and confined spaces where longer bits are impractical.
