Screw Machine Drill Bit 3/16 in
This carbide drill bit targets machinists and maintenance technicians who need precise holes in steel and cast iron. Its 118-degree point angle and four-facet geometry reduce walk and deliver clean entry in screw-machine operations.
Sustained Cutting Behaviour
The uncoated carbide substrate resists heat buildup during repetitive drilling cycles without coolant-through capability. Right-hand cutting direction and the 118-degree point maintain consistent chip formation and dimensional accuracy across long production runs.
Build And Mounting Implications
Bright finish eliminates coating delamination concerns when regrinding the four-facet point. Straight shank fits standard collets and chucks, while the 0.1875 decimal equivalent simplifies tool-offset programming for CNC screw machines.

Questions about this item
How much heat does the 118-degree point generate during continuous drilling?
The 118-degree point angle is designed for general-purpose drilling and reduces thrust force, which helps manage heat buildup during extended use in materials like steel or cast iron.
What shank size must my drill chuck accept for the 3/16-inch bit to fit?
The bit has a 3/16-inch diameter shank, so your drill chuck must accommodate at least 0.1875 inches to hold it securely.
Will the 118-degree point work effectively with older low-speed drill presses?
Yes, the 118-degree point angle and right-hand cutting direction are compatible with older drill presses running at lower speeds for general-purpose drilling tasks.
