Meet the Dormer Pramet A110 20.00 mm HSS ST Straight Shank Long Series Drill, a purpose-built tool for deep, precise holemaking in a variety of materials. Engineered to DIN 340 standards, this drill combines a robust 118-degree conventional point with a long reach that helps you tackle deep pockets, through-holes, and hard-to-reach workpieces with confidence.

• 118° conventional point delivers aggressive starts, reduces wandering, and is straightforward to re-sharpen for extended tool life.
• Steam oxide finish minimizes workpiece material from sticking to the cutting edge, promoting cleaner holes and smoother chip flow.
• Long length series provides increased reach for deeper holes and longer workpieces, making it ideal for automotive, fabrication, and maintenance tasks.
• Premium HSS material handles drilling a wide range of materials—steel, aluminum, stainless steel—with reliable sharpness and durability.
• Versatile, straight shank design supports both handheld and machine drilling, compatible with common chucks and spindle interfaces (DIN 340).

Ideal for professionals who need dependable, high-performance holemaking in tight spaces, the A110 long-series drill excels in repeatedly delivering true starts and clean, accurate holes in a variety of metals. Whether you’re assembling components, fabricating frames, or performing on-site maintenance, this drill reduces downtime and boosts productivity by delivering consistent results across projects.

Use cases and practicality

• Deep-hole drilling in steel, aluminum, and stainless steel for automotive parts, machinery housings, and structural components.
• Hand-held or machine-assisted drilling where reach is critical, such as fixtures, jigs, and assemblies with limited access.
• Maintenance tasks requiring a long-reach drill that won’t compromise hole accuracy or edge life.

Why this drill stands out in real-world work

• The 118° point starts quickly and holds its geometry well, reducing the need for corrective passes in familiar materials.
• The steam oxide coating helps prevent tool-lift and hot-charging effects, enabling more consistent cutting performance over longer sessions.
• The extended length consolidates what would otherwise require multiple tools, saving time on set-ups and changing tools mid-project.

Care and best practices

• Keep feeds steady and apply appropriate lubrication to maintain cutting edge temperature and prolong life.
• Re-sharpen when the edge shows signs of wear to preserve hole size accuracy and edge geometry.
• Ensure a true fit in the chuck or spindle to minimize runout and maximize hole concentricity.
