Description
The KnKut 3/16" Fractional Jobber Length Drill Bit (KK5-3/16) is engineered for precise and efficient drilling in some of the most demanding materials. Crafted from premium-grade Molybdenum High-Speed Steel with a high vanadium content, this drill bit is designed for superior performance and longevity. A key differentiator is its salt nitride treatment, a process that actually penetrates the tool's surface, enhancing its hardness. This specialized treatment enables the KnKut KK5-3/16 to effectively drill through tough materials such as stainless steel and titanium alloy, where standard drill bits often fall short. The 135° split point tip is a significant advantage, eliminating the need for a center punch or pilot hole, which ensures a more accurate start and results in rounder, cleaner holes. Made entirely in the USA, this drill bit reflects a commitment to quality manufacturing and consistent performance in various industrial and workshop applications.
KEY FEATURES AND BENEFITS:
- Optimized for Tough Materials: Specifically designed to drill stainless steel and titanium alloy with efficiency due to its unique material composition and treatment.
- Self-Centering 135° Split Point: Starts drilling immediately without walking, eliminating the need for a center punch or pilot hole, saving time and improving accuracy.
- Enhanced Surface Hardness: Salt nitride treatment penetrates the tool's surface, providing superior hardness for extended tool life and consistent performance in challenging applications.
- Secure Chuck Grip: Features three flats on the shank (for 3/16" and larger sizes) to prevent slippage in the drill chuck, ensuring stable and safe operation.
- Cost-Effective Drilling: Engineered for durability and extended sharpness, contributing to a lower cost per hole over the tool's lifespan.
- Made in USA Quality: Manufactured domestically, ensuring high standards of quality control and reliable performance.

HOW TO USE:
- Secure the Drill Bit: Insert the KnKut 3/16" drill bit into your drill's chuck. Ensure it is tightened securely by closing all three jaws of the chuck firmly to prevent any wobble or slippage during operation.
- Prepare the Material: Mark the desired drilling location on your material. No center punch is required due to the drill bit's 135° split point design.
- Apply Cutting Fluid: For drilling ferrous or non-ferrous metals, apply a suitable cutting fluid to the drilling area. This helps to cool the drill bit, lubricate the cut, and prolong the life of the tool while improving the quality of the hole.
- Start Drilling: Position the drill bit's tip directly on your mark. Begin drilling by applying firm, steady pressure before engaging the drill's rotation. This prevents the bit from "walking" or dulling prematurely.
- Maintain Pressure and Speed: Continue to apply consistent pressure throughout the drilling process. Adjust the drill's RPM (revolutions per minute) based on the material being drilled; harder materials generally require lower speeds. Observe the chip formation; a continuous strand indicates proper drilling for most metals.
- Clear Chips and Finish: Periodically back the drill bit out to clear chips from the hole, especially in deeper applications. Once the hole is complete, release pressure and carefully remove the drill bit from the material.
BENEFITS OF USING KNKUT 3/16" FRACTIONAL JOBBER LENGTH DRILL BIT (KK5-3/16):
- Exceptional Durability: The combination of high-grade Molybdenum HSS, high vanadium content, and salt nitride treatment significantly extends the lifespan of the drill bit, even when used on hard materials.
- Superior Hole Quality: Consistently produces clean, round, and accurate holes, reducing the need for secondary finishing operations.
- Increased Productivity: The 135° split point allows for faster starts and eliminates pre-drilling steps, improving overall work efficiency.
- Reduced Tool Replacement: Its robust construction and treatment mean fewer drill bit changes, saving time and reducing consumable costs.
- Reliable Performance: Engineered and manufactured in the USA to stringent quality standards, ensuring consistent and dependable results in various applications.
FEATURES:
- Enhanced wear resistance from high vanadium content in premium Molybdenum High-Speed Steel.
- Deep salt nitride surface treatment increases tool hardness and life.
- Prevents walking and ensures precision on both flat and curved surfaces.
- Three flat shank design maximizes grip security in drill chucks.
- Long-lasting sharpness for improved cutting performance over time.
- Suitable for intensive use in aerospace, automotive, and metal fabrication settings.
- Right-hand cutting direction ideal for standard drilling operations.
