Frequently Asked Questions
What is a Morse taper shank?
A Morse taper shank is a self-locking taper that secures the drill into the spindle of a machine tool. It provides high torque transmission and accurate alignment, making it essential for heavy drilling applications.
Are these long twist drills suitable for marine use?
Yes. They are made from high-speed steel and precision-ground to handle the tough materials encountered in marine engineering, including steel, stainless steel, and aluminum. The long series design is perfect for deep-hole drilling in ship hulls and machinery.
What sizes are available?
We stock a range of diameters from 3 mm to 50 mm, with Morse taper sizes MT1 to MT5. The overall length varies from 100 mm to 400 mm, depending on the diameter and shank size.
Can these drills be used in a hand drill?
They are designed for machines with a Morse taper socket. You can use them with a hand drill by fitting a Morse taper adapter into a standard drill chuck, but for optimal performance, a drill press or lathe is recommended.
