Broca Bosch 8 mm HSS modelo 2608833777 para metal y taladrado general

Bosch 8 mm HSS drill bit model 2608833777 is a high-speed steel twist bit designed for drilling through metal and general-purpose materials. The 8 mm diameter and standard flute geometry provide precise, clean holes for fastening, assembly and repair tasks. Constructed from HSS, the bit balances hardness and toughness to resist wear and tolerate elevated temperatures generated during continuous drilling operations in workshops and on-site jobs.

Advantages

The HSS material offers good heat resistance and edge retention, reducing the need for frequent resharpening under normal working conditions. The twist design ensures efficient chip removal and stable drilling when used with both handheld drills and powered drill presses. Compatibility with common drill chucks and a straight shank make the bit easy to mount and position for accurate hole placement.

Suitable for

• Drilling through mild and medium-hard metals (steel, iron, aluminium)
• Workshop and maintenance drilling tasks
• General-purpose holes in wood, plastics and composite materials
• Handheld electric drills and bench drill presses

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 8 mm
• Type: Twist drill bit with straight shank
• Primary use: Metal and general-purpose drilling
• Compatibility: Standard drill chucks for handheld and machine use

How to use

Select a suitable drill speed and feed for the work material and secure the workpiece before drilling. Fit the 8 mm HSS bit into the drill chuck and tighten firmly. Use cutting fluid or coolant when drilling metals to reduce heat and prolong tool life; apply steady pressure without forcing the bit. Clear chips periodically and allow the bit to cool during prolonged drilling to maintain cutting performance and accuracy.

Recommendations

For best results when drilling metal, start with a pilot hole if drilling large or deep holes, maintain an appropriate rotational speed for the material, and use cutting lubricant to reduce friction and improve hole quality. Inspect the bit for wear and resharpen or replace when edges become dull to avoid poor hole accuracy and increased breakage risk.
