Drill bit Proline 91011, metal drill bit, Ø10 mm, length 110 mm, 1 pc

Proline 91011 metal drill bit, Ø10 mm and 110 mm long, is a single-piece cutting tool intended for drilling metal. The bit is designed for use with hand drills and drill presses and is suited to create precise holes in sheet metal, profiles and structural components during repair and fabrication work. Supplied as one piece, the drill bit balances length and diameter for common metalworking tasks requiring a 10 mm bore.

Advantages

The drill bit incorporates a hard-point cutting geometry that improves durability and provides accurate centered drilling. Its construction reduces drill load during cutting, helping maintain straight bores and extending service life under typical metal drilling conditions. The 110 mm length gives additional reach for through-holes or when working on thicker assemblies, while compatibility with standard chucks makes it ready for both portable and fixed drilling equipment.

Suitable for

• Drilling holes in sheet metal and thin-walled components
• Making bores in steel profiles and structural metal parts
• Repair, maintenance and fabrication tasks requiring a 10 mm hole
• Use with hand drills and drill presses

Key specifications

• Diameter: 10 mm
• Overall length: 110 mm
• Material application: metal
• Pack quantity: 1 piece
• Tip style: hard-point cutting geometry for centered drilling

How to use

Secure the Proline 91011 drill bit in the drill chuck and tighten firmly. Mark the drilling point on the workpiece and, if needed, use a center punch to prevent wandering. Set an appropriate spindle speed for the metal type being drilled and apply steady, moderate feed pressure. Use cutting lubricant when drilling harder steels to reduce heat and wear. Retract occasionally to clear chips when drilling deep holes and allow the bit to cool between long runs.

Usage recommendations

Use appropriate personal protective equipment, clamp the workpiece securely and select speed/feed based on material hardness. For best results on thicker or harder metals, apply cutting fluid and avoid excessive side loading to preserve tip geometry and prolong bit life.
