KnKut 29-Piece Short Stubby Drill Bit Set 1/16″-1/2″ by 64ths (29KK7)

Description

The KnKut 29-Piece Short Stubby Drill Bit Set 1/16″-1/2″ by 64ths (29KK7) is a professional-grade solution for drilling in confined spaces and through challenging materials. Crafted in the USA from premium Hi-Molybdenum high-speed steel with high vanadium content, these bits are engineered for exceptional performance. Each bit undergoes a unique salt nitride treatment, which penetrates the tool’s surface, significantly increasing its hardness and making it ideal for penetrating tough alloys like stainless steel and titanium. The short stubby length provides enhanced rigidity, reducing bit deflection and breakage, while the 135° split point tip allows for direct drilling without the need for a center punch or pilot hole. This design promotes faster penetration and consistently produces rounder, more accurate holes. With a comprehensive range of 29 fractional sizes from 1/16″ to 1/2″ by 64ths, this set offers versatility and precision for a wide array of demanding drilling applications.

KEY FEATURES AND BENEFITS:

• Optimized for Tough Materials: Manufactured from high-grade Hi-Molybdenum high-speed steel with high vanadium content, specifically designed to penetrate challenging materials like stainless steel and titanium alloy efficiently.
• Enhanced Hardness and Longevity: Features a salt nitride treatment that penetrates the tool’s surface, providing superior hardness and extending the bit’s lifespan, even in demanding applications.
• No Pilot Hole Required: The 135° Split Point Tip allows for immediate drilling without the need for a center punch or pilot hole, saving time and increasing efficiency.
• Superior Hole Accuracy: Engineered to produce rounder, more accurate holes, ensuring precise results for critical applications.
• Cost-Effective Drilling: The durability and efficiency of these bits contribute to a lower cost per hole, reducing replacement frequency and labor time.
• Ideal for Confined Spaces: The short stubby length provides increased rigidity and reduced breakage, making it perfect for drilling in tight or limited access areas.

HOW TO USE:

1. Select the Correct Bit Size: Identify the appropriate drill bit size (from 1/16″ to 1/2″ by 64ths) for your application from the set.
2. Secure the Bit: Insert the chosen drill bit firmly into your drill’s chuck, ensuring it is centered and tightened securely. For bits 3/16″ and larger, align the chuck jaws with the three flats on the shank for a better grip.
3. Position for Drilling: Place the tip of the drill bit directly onto the material where you wish to drill. Due to the 135° split point, a center punch or pilot hole is not necessary.
4. Apply Consistent Pressure: Begin drilling with moderate, consistent pressure, allowing the bit to do the work. Avoid excessive force, especially when starting, as the split point design helps prevent “walking.”
5. Maintain Proper Speed: Use an appropriate drill speed for the material you are drilling. Slower speeds are generally recommended for harder materials like stainless steel and titanium to prevent overheating.
6. Clear Chips: Periodically withdraw the bit slightly or use a peck drilling motion to clear chips from the hole, especially when drilling deeper holes in tough materials. This helps prevent chip build-up and keeps the bit cool.
7. Clean and Store: After use, clean the drill bit and return it to its designated spot in the storage case to protect it and keep the set organized.
