Drill bit Abraboro HSS cylindrical 13 mm set of 5 (AB00011301)

Abraboro HSS cylindrical 13 mm drill bits in a set of five provide a consistent solution for drilling 13 mm diameter holes in metal and other common materials. Made from high-speed steel (HSS), these bits are designed for general-purpose workshop and maintenance tasks where repeatable hole size and reliable cutting performance are required. The cylindrical shank allows secure clamping in standard chucks and straightforward replacement during repetitive operations.

Advantages

High-speed steel construction ensures good wear resistance and heat tolerance under typical drilling speeds. The cylindrical shank design fits standard chucks for secure grip and easy bit changes. Supplied as a set of five, the pack reduces downtime by providing spare bits for continuous work. The geometry of the cutting edges is suitable for clean penetration into metals and other common engineering materials when used with appropriate speeds and lubrication.

Suitable for

• Drilling 13 mm holes in steel, cast iron and non-ferrous metals
• Workshop maintenance and repair tasks
• Production operations requiring repeatable hole diameters
• Drilling in sheet metal and medium-thickness plates

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 13 mm
• Shank type: Cylindrical shank for standard chucks
• Quantity: Set of 5 drill bits
• Intended use: Cutting/drilling in metal and common engineering materials

How to use

Select a suitable drilling machine or hand drill with a chuck that accepts cylindrical shanks. Securely clamp the 13 mm drill bit in the chuck, ensuring proper alignment and tightness. Mark and, if needed, center-punch the drilling location to improve accuracy. Use appropriate spindle speed for HSS bits and the material being drilled; apply cutting fluid or lubrication when drilling steels to reduce heat and extend bit life. Apply steady feed pressure, withdraw occasionally to clear chips, and finish the hole to the required depth.

Usage recommendations

For best results when drilling steels and harder alloys, use moderate speed and cutting fluid to prevent overheating. Replace worn bits from the set to maintain hole quality. For thin sheet materials, support the workpiece to avoid bending and burr formation.
