Key Features

• BB2055 basic coated series: coated carbide drill for steel machining.
• Wide diameter coverage: available from 0.5mm to 25.0mm across the variant range.
• Regular-length design: a practical first choice before selecting longer drill versions.
• Spiral flute design: supports chip evacuation and helps reduce chip buildup during drilling.
• Rigid carbide construction: suitable for CNC machines, milling machines, drill presses, and other stable setups.

Series Selection

• BF2045: uncoated aluminum-use series for aluminum, copper, plastics, and similar non-ferrous or non-metal materials.
• BB2055: basic coated series for steel machining.
• BL2060: upgraded blue nano coated series with higher wear resistance.

How to Choose

• Choose the required drill diameter from the variant list.
• Choose BB2055 when you need BB Tool’s basic coated carbide drill for steel.
• For deeper reach, choose the BB2055 long drill pages by overall length.
• If a shorter drill can reach the hole, it is usually more rigid and easier to control.

Usage Notes

• Recommended for CNC machines, drill presses, milling machines, and other rigid drilling setups.
• Handheld electric drills and impact drills are not recommended. Solid carbide drills are hard but brittle, and unstable hand feed, vibration, or runout can cause chipping or breakage.
• Use accurate clamping and keep tool runout as low as possible.
• Use suitable coolant or chip-clearing strategy according to the material and drilling depth.
• Do not use this carbide drill for concrete, tile, glass, or similar brittle construction materials.
• If the cutting edge is chipped or cracked, stop using the tool to avoid safety risk or workpiece damage.
