High speed steel
FUNCTION - Center and registration drills are traditionally used to create a tapered hole for a lathe center to create a starting point for a standard twist drill designed to keep the drill from running.
DESIGN- Each drill bit has a double end and is ground with a standard 60 degree angle included.
FIT- Used for the production of center supports in components or workpieces requiring center-to-center machining.
MATERIAL- Material: HSS, applicable hardness: HRC40 or less.
SIZE- The set includes 5 dimensions: 1.5mm tip diameter with 5mm body diameter and 35mm length and 2.0mm tip diameter with 5mm body diameter and 41mm length and tip diameter of 2.5mm with body diameter of 6mm and length of 45mm And tip diameter of 3mm with body diameter of 8mm and length of 51mm and tip diameter of 4mm with diameter of 10 mm body and 60 mm length.
These center drills are used in metalworking to provide a starting hole for a larger size drill bit.
They can also be used to make a taper indentation at the end of a workpiece to mount a lathe center.
Made of high speed steel, these center drills are of high hardness and good wear resistance.
There are 5 piece center bits in this set which can be used to punch holes in various sizes.
Widely used on lathe machines, these center drills can cut easily and remove chips smoothly.
Registration and registration exercises are traditionally used to form a tapered hole for a lathe center to be a starting point for a standard twist drill,
Designed to keep the drill from running.
Used for the production of center supports in components or workpieces requiring machining between centers.
When using these drill bits, the temperature of the material (e.g., mild metal, mild steel, aluminum, acrylic plastic and wood, etc.) will be very high, add water or coolant to prevent the product does not smoke when in use.
