Hertel C.402.0225 Jobber Drill 2.25mm Hss 118 Deg

Product Description

The HERTEL C.402.0225 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It features a 118-degree standard point angle that provides a versatile cutting geometry suited to a wide range of workpiece materials. The bit measures 2.25 mm (0.0886 inches) in diameter with an overall length of 57 mm and a 32 mm flute length. An oxide coating reduces friction and provides light surface protection during cutting. With a straight-cylindrical shank, it seats securely in standard drill chucks and collets. Machinists, tool-and-die technicians, and maintenance professionals install this bit for everyday drilling tasks.

This jobber drill is suited for light-duty to medium-duty drilling operations in shop and field environments. The 2.25 mm diameter places it in the 2.00 mm to 3.00 mm size range, making it appropriate for tapping prep holes, pilot holes, and precision through-holes in ferrous and non-ferrous materials. The spiral flute design promotes chip evacuation during drilling. This bit is sold individually and is well suited for use in drill presses, hand drills, and CNC machining centers running appropriate feed and speed parameters for HSS tooling.

Key Features

• 2.25 mm (0.0886 inch) diameter for precise small-hole drilling
• 118-degree standard point angle for general-purpose versatility across common materials
• High speed steel construction provides toughness and resistance to heat buildup
• Oxide coating reduces friction and offers light corrosion resistance
• Spiral flute geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber drill compatible with standard drill chucks and collets sized for straight-cylindrical shanks in the 2.00 mm to 3.00 mm drill bit range.

Installation Notes

This bit is installed and changed by machinists, maintenance technicians, and tool operators. Ensure the drill press or hand drill is powered off and the chuck is fully released before inserting or removing the bit. Secure the shank firmly in the chuck to prevent slippage during operation. Use appropriate feed rates and cutting speeds for high speed steel tooling and the specific workpiece material to avoid premature wear or bit breakage.
