Dormer A110 HSS Long Series Drill 8.50mm OL:165mm WL:109mm | A1108.5

Dormer A1108.5 HSS Long Series Drill Bit (8.50mm, 165mm OAL, 109mm WL)

Dormer A1108.5 is an HSS long series drill bit designed for deeper-hole drilling where extra reach is required, while keeping a straightforward, trade-friendly geometry for everyday metalworking tasks. With an 8.50mm tip diameter, it’s a practical choice for workshop and site users who need reliable hole-making in common materials.

The A110 long series pattern provides extended overall length for improved access in restricted positions, making it a solid option when standard-length drill bits won’t reach the job.

Key Features

• Long series reach: Extended overall length helps you drill deeper holes and reach recessed positions more easily than standard-length bits.
• HSS construction: High speed steel is suited to general-purpose drilling where toughness and durability are required.
• 118° point angle: A practical, general-purpose point geometry for a wide range of drilling work.
• DIN 340 type: Long series pattern commonly specified for deep-hole drilling applications.
• 8.50mm diameter: Suitable for producing accurately sized holes when paired with the correct drilling setup and cutting fluid.
