## Summary description

Conical HSS drill bit Abraboro, 28.0 mm diameter (model AB44528000). Designed for metalworking, the high-speed steel (HSS) construction provides wear resistance and heat tolerance for drilling into various ferrous and non-ferrous metals. Suitable for use with drill presses and handheld drills for creating tapered holes, deburring, and enlarging existing holes in metal components.

## Long description

Conical HSS drill bit Abraboro 28.0 mm (model AB44528000) is a high-speed steel cutting tool designed for metalworking applications. Its conical geometry enables gradual enlargement of holes and creation of tapered bores, while the HSS material offers wear resistance and heat tolerance for use on a variety of ferrous and non-ferrous metals. The bit is suitable for both drill presses and handheld drills, providing controlled material removal when deburring, countersinking or enlarging existing holes in metal components.
Advantages
The HSS construction delivers reliable hardness and thermal stability during continuous drilling operations, reducing premature wear. The conical shape provides progressive cutting action that minimizes chatter and allows precise control of hole diameter. The geometry is suitable for working with steels, aluminum and other common metals, and its robust design supports use in both stationary and portable drilling tools.
Suitable for
 Enlarging existing holes in metal components
 Creating tapered or countersunk bores
 Deburring and smoothing metal edges
 Use with drill presses and handheld electric drills
Key specifications
 Material: High-speed steel (HSS)
 Tip shape: Conical (tapered) geometry
 Nominal diameter: 28.0 mm
 Typical applications: Ferrous and non-ferrous metals
 Compatible tool types: Drill press and handheld drill
How to use
Secure the workpiece to prevent movement and select an appropriate drill speed for the material being worked; lower speeds are generally recommended for harder steels, while higher speeds can be used for softer metals such as aluminum. Fit the conical HSS bit into the drill chuck and ensure it is firmly clamped. Apply steady, moderate pressure and allow the tapered profile to progressively enlarge the hole—avoid excessive feed that can cause overheating. Use cutting fluid or lubricant when drilling steel to extend tool life and improve finish. After use, clean chips from the flutes and store the bit in a dry location.
Usage recommendations
For best results, start with a pilot hole when creating a specific final diameter or when working with thicker material. Use appropriate personal protective equipment (eye protection and gloves) and cooling lubricant when working with ferrous metals. Inspect the cutting edge regularly and replace the bit if excessive wear or chipping appears to maintain accuracy and safety.
