The KnKut 13pc Hex M35 Jobber Drill Bit Set 1/16"-1/4" by 64ths (13KK35) offers precision and reliability for drilling through challenging materials. Crafted from M35 Cobalt High-Speed Steel and proudly made in the USA, this set is engineered to handle high-tensile and work-hardening metals. Each bit features a 135° split point, allowing for immediate starts without the need for a center punch or pilot hole, ensuring accurate drilling from the very first contact. For enhanced stability, bits 3/16" and larger are equipped with hex shanks, which securely grip your drill chuck and prevent slippage during demanding applications. The specialized straw finish further contributes to the drill bits' heat resistance, helping them maintain their sharpness and extend their operational life. This set is an essential addition for professionals working with materials such as high-strength alloy steels, stainless steel, titanium, manganese steel, and armor plate. KEY FEATURES AND BENEFITS: Exceptional Material Composition: Made from M35 Cobalt High-Speed Steel, these bits provide superior heat resistance, ensuring they stay sharp longer when drilling tough metals. Precision Drilling: The 135° split point design allows the bit to start on contact, preventing "walking" and eliminating the need for a center punch or pilot hole, leading to cleaner, more accurate holes. Secure Grip: Hex shanks on bits 3/16" and above ensure a firm, non-slip grip in your drill chuck, enhancing safety and efficiency during high-torque applications. Extended Tool Life: The M35 Cobalt material and specialized straw finish contribute to the drill bits' longevity, offering consistent performance through numerous projects. Versatile Application: Specifically engineered to perform effectively on a wide range of difficult-to-drill materials, including high-strength alloy steels, stainless steel, titanium, manganese steel, and armor plate. Made in USA Quality: Manufactured in the United States, guaranteeing a high standard of craftsmanship and material quality from production to delivery. SPECIFICATIONS: Set Size: 13 pieces Drill Bit Sizes: 1/16" - 1/4" by 64ths Material: M35 Cobalt High-Speed Steel Point Angle: 135° Split Point Shank Type: Hex (on sizes 3/16" and above) Finish: Straw Manufacturing Origin: USA Included in Product: 13 individual drill bits in the specified size range. HOW TO USE: Select the Correct Bit: Choose the appropriate drill bit size for your application from the 13-piece set. Secure the Bit: Insert the drill bit into your drill chuck. For bits 3/16" and larger, ensure the hex shank is properly aligned. Tighten the chuck securely, making sure to tighten all three jaws of the chuck for optimal grip and to prevent slippage. Apply Cutting Oil (Recommended): Before drilling, apply a suitable cutting oil to the workpiece where you intend to drill. This helps reduce friction and heat, extending the life of your drill bit and improving drilling performance. Position and Apply Pressure: Position the drill bit directly onto the desired drilling spot. Apply firm, consistent pressure to the drill before engaging the power. This helps the 135° split point to start precisely on contact and prevents the bit from "walking" or skidding across the surface. Start Drilling: Begin drilling at the appropriate RPM for the material and drill bit size. Adjust the speed and pressure as you drill; you should aim for a continuous strand of material exiting the hole, which indicates efficient cutting. Monitor and Maintain: Continue drilling, periodically clearing chips and reapplying cutting oil as needed. Once the hole is complete, carefully withdraw the drill bit. BENEFITS OF USING KNKUT 13PC HEX M35 JOBBER DRILL BIT SET 1/16"-1/4" BY 64THS (13KK35): Reliable Performance on Tough Metals: Engineered to consistently drill through materials that challenge standard drill bits, such as stainless steel and titanium, reducing project delays. Enhanced Drilling Accuracy: The unique tip design allows for self-starting without pre-drilling, leading to straighter, more precisely located holes every time. Increased Productivity: Reduced bit slippage due to hex shanks means less time wasted readjusting and more efficient drilling operations. Cost-Effective Over Time: The extended lifespan from the M35 Cobalt material means fewer bit replacements, offering better value for your investment compared to less robust alternatives. Reduced User Fatigue: The design promotes smoother drilling, potentially lowering the physical effort required, especially when working on dense materials. FEATURES: Constructed with high-performance M35 Cobalt steel for enhanced durability. Withstands high heat, helping maintain sharp cutting edges. 135° split point provides clean starts and minimizes bit walking. Hex shanks (3/16" and above) ensure firm engagement with the drill chuck. Straw finish assists in heat dissipation during extended use. Compatible with both manual and powered drilling tools. Designed for heavy-duty applications in work-hardened metals. Eliminates the need for pre-drilling or center punching. Made in the USA with stringent quality standards. Offers a full range of fractional sizes from 1/16" to 1/4".
