HOW TO USE:

1. Select the Correct Bit: Choose the appropriate drill bit size from the set for your specific application.
2. Secure the Workpiece: Ensure the material you are drilling is firmly secured to prevent movement during the drilling process.
3. Insert Bit into Drill: Insert the drill bit securely into the chuck of your drill (corded or cordless, standard or right-angle). Ensure it's tightened properly to prevent slippage.
4. Determine Speed: For harder materials like stainless steel or titanium, use a slower drill speed. For softer materials, a higher speed may be appropriate. Refer to your drill's manual or material guidelines if unsure.
5. Apply Consistent Pressure: Begin drilling by applying firm, consistent pressure to the drill. The 135-degree split point will help the bit start without walking.
6. Maintain Lubrication (Optional but Recommended): For extended bit life and to prevent overheating, especially when drilling metals, consider using cutting fluid or lubricant.
7. Clear Chips: Periodically withdraw the bit slightly to clear chips from the hole, especially when drilling deeper holes, to prevent clogging and overheating.
8. Complete the Hole: Continue drilling until the desired depth is reached or the bit passes through the material.
9. Remove Bit and Clean: Once done, remove the bit from the chuck and clean any debris. Store the bits in their metal case to protect them.

BENEFITS OF USING KNKUT 21-PIECE SHORT STUBBY DRILL BIT SET 1/16"-3/8" BY 64THS (21KK7):

• Exceptional Rigidity: The short stubby length provides inherent rigidity, which significantly reduces bit deflection and breakage, especially in demanding drilling tasks or tight spaces.
• Enhanced Material Penetration: The specific combination of Hi-Molybdenum HSS, high vanadium content, and salt nitride treatment allows for superior penetration and cutting ability in extremely hard materials.
• Time and Cost Efficiency: The ability to drill without a pilot hole and the extended tool life result in less downtime for bit changes and fewer bit replacements, saving both time and money.
• Consistent Hole Quality: The 135-degree split point ensures a precise start and maintains accuracy throughout the drilling process, leading to consistently round and clean holes.
• Versatility in Applications: While ideal for tough metals, these bits are also highly effective on a wide range of other materials, making them a versatile addition to any toolbox.

FEATURES:

• Manufactured with a high vanadium content within the steel for added toughness.
• Surface treated with a salt nitride process that diffuses nitrogen into the material for increased hardness.
• Specifically engineered for optimal performance when drilling high-strength alloys.
• The compact screw-machine length offers superior stability during operation.
• Self-centering tip design eliminates the need for pre-drilling.
• Designed to provide maximum lubricity during the cutting process, reducing friction.
• Comes organized in a durable, robust metal storage index case.
• Optimized for applications requiring precise hole alignment.
