3/16-Inch Parabolic Jobber Drill Bit
This cobalt-steel jobber drill bit measures 3/16 inch with a 135-degree notch point. The TiAlN coating reduces friction and heat during high-speed drilling. Its parabolic flute design improves chip evacuation in deep holes. Right-hand cutting direction suits standard drill chucks and CNC tool holders.
Capacity and headroom in steel and alloy
The 3-1/2-inch overall length and 2-15/16-inch flute length provide reach for through-holes in structural steel and titanium alloys. Cobalt substrate maintains edge hardness at elevated temperatures where standard HSS dulls quickly. TiAlN finish extends tool life in abrasive materials such as cast iron and hardened stainless. Non-coolant-through design limits use in deep-hole applications requiring internal lubrication.
Upgrade from general-purpose HSS bits
Replaces standard 135-degree split-point HSS bits when hole quality and tool life in tough alloys are critical. The parabolic flute geometry clears chips more reliably than conventional flutes in depths beyond three diameters. Notch point geometry reduces walk on curved or angled surfaces without centre drilling. Not suited for buyers needing coolant-fed operation or carbide-tipped performance in high-volume production.

Questions about this item
Will the 3/16 inch shank fit the chuck on my older drill press?
The shank diameter is 3/16 inch, matching standard fractional-inch chucks found on most older drill presses and hand drills.
How can I confirm the 135 degree point angle is cutting correctly in cobalt steel?
A properly sharpened 135 degree notch point should self-centre without a pilot hole and produce short, curled chips in steel rather than long strings.
Does the box include cutting fluid or a case for the TiAlN coated bit?
The item is supplied as a single jobber drill bit only; cutting fluid and a storage case must be purchased separately.
