Hertel H95006214 Jobber Drill Bit Letter O 137 Deg

Product Description

The HERTEL H95006214 is a Letter O jobber-length drill bit designed for general-purpose holemaking in metal and other materials commonly encountered in trade and industrial applications. Built from heavy-duty high speed steel with an oxide finish, this bit produces a 0.3160 inch diameter hole with a 137-degree split point that reduces walking and minimizes the need for a center punch. The right-hand spiral flute geometry clears chips efficiently during through-hole drilling. With an overall length of 4.375 inches and a flute length of 2.375 inches, the H95006214 fits standard three-flat drill chucks and is compatible with both handheld and bench-mounted drilling equipment.

This drill bit is suited for electricians, plumbers, HVAC technicians, and maintenance trades who need reliable holemaking on ferrous and non-ferrous materials in the field or shop. The jobber-length series balances reach and rigidity for everyday drilling tasks where a standard chuck depth and moderate flute length are appropriate. The heavy-duty grade makes it a practical choice for repetitive use on steel, cast iron, aluminum, and similar base materials encountered in mechanical and construction trades.

Key Features

• Letter O size produces a 0.3160 inch diameter hole conforming to ANSI specification
• 137-degree split point reduces drill walk and starting pressure on hard surfaces
• High speed steel construction with oxide finish for heat and wear resistance
• Heavy-duty grade rating for repetitive and demanding drilling applications
• Right-hand cut with regular spiral and 2-flute geometry for efficient chip evacuation
• Three-flat shank for positive chuck engagement and reduced slipping

Compatibility

Designed as an OEM-style jobber drill bit for use in standard 3-flat keyed or keyless drill chucks accepting round and flat-shank bits in the 0.3000 to 0.3500 inch size range.

Installation Notes

This bit is installed and operated by electricians, plumbers, HVAC technicians, pipefitters, and general maintenance trades using portable or stationary drilling equipment. Secure the three-flat shank firmly in the chuck before use to prevent slipping under load. When drilling hard steel or thick stock, use cutting fluid to extend bit life and reduce heat buildup. Inspect the cutting edges and split point for wear or chipping before each use and replace the bit if edge integrity is compromised.
