Cle-Line C23484 7/16 in Drill Bit
This Cle-Line screw machine drill bit has a 7/16 inch diameter and a 135 degree split point. It is made from high speed steel with a black oxide finish for general purpose drilling. The right hand cutting direction suits standard drill motors and drill presses. It is designed for machinists and maintenance technicians creating precise holes in metal.
Suited for metal drilling, not for masonry or wood
The split point geometry reduces walking on hard materials like steel and alloy. Builders who need to drill concrete, brick or tile should choose a masonry bit instead. Woodworkers requiring clean entry in timber will find brad point or spur bits more appropriate. This bit is not coolant through so deep holes may require manual lubrication.
135 degree split point for self-centering starts
The 135 degree split point allows the bit to start on contact without a centre punch. This improves hole accuracy in metalworking and reduces thrust force needed. The decimal equivalent is .4375 inch for precise tolerance calculations. High speed steel construction balances wear resistance and toughness for repetitive screw machine use.

Questions about this item
How does the 135° split point perform under sustained drilling?
The 135° split point centres quickly and reduces wandering, letting the bit cut efficiently through metal without excessive pressure during extended use.
Does the black oxide finish affect heat or noise during all-day operation?
Black oxide helps retain lubricant and resists heat buildup, so the bit runs cooler and quieter than uncoated high-speed steel in repetitive drilling.
What shank size must my drill chuck accept for this 7/16 in bit?
The bit has a straight shank matching its 7/16 in diameter, so your chuck must open to at least 0.4375 in to hold it securely.
