Hertel H95006209 Jobber Drill Bit Letter J Hss

Product Description

The HERTEL H95006209 is a Letter J jobber-length drill bit designed for general-purpose holemaking in metal, wood, and composite materials. Built from high speed steel with an oxide and TiN coating, it delivers extended tool life in production and maintenance drilling applications. The 137-degree split point reduces walking and requires no center punch on most surfaces. At 4.125 inches overall length with a 2.25-inch flute length, it fits standard drill chucks and is sized for holes at 0.2770 inches (decimal). This bit is a go-to for machinists, maintenance techs, and industrial tradespeople who need a reliable, heavy-duty jobber drill.

This drill bit is suited for holemaking tasks across residential, commercial, and light industrial settings. It is commonly used in HVAC, plumbing, and electrical rough-in work where drilling through sheet metal, steel brackets, pipe hangers, or structural steel is required. The right-hand spiral flute and two-flute geometry clear chips efficiently during through-hole drilling. Trades that regularly stock jobber drill sets — including pipefitters, sheet metal workers, and electricians — will find this a standard replacement or add-on for their Letter J size.

Key Features

• 137-degree split point reduces drill walking and improves hole entry accuracy
• High speed steel construction with oxide and TiN coating for extended wear resistance
• Two-flute right-hand spiral design promotes efficient chip evacuation
• Heavy-duty grade rated for demanding production and maintenance drilling
• Three flats on the shank reduce slippage in drill chuck
• ANSI specification designation ensures consistent sizing and dimensional accuracy

Compatibility

Designed as an OEM-style jobber drill bit for use in any standard drill chuck that accepts a 0.2770-inch shank, compatible with handheld drills, drill presses, and machining centers requiring a Letter J size bit.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotary cutting tools. Always secure the workpiece and confirm chuck tightness before operation. Use appropriate cutting fluid or coolant on hard metals to reduce heat buildup and prolong bit life. Inspect the cutting edges for wear or chipping before each use and replace if the point geometry is compromised.
