Chicago-Latrobe 46616 Jobber Drill Bit
The Chicago-Latrobe 46616 is a jobber length drill bit built for general-purpose drilling in metal, wood and plastic. It suits trade professionals and DIY users who need a reliable 1/4 inch fractional size bit for everyday workshop tasks.
135° Cobalt Split Point
The single specification that decides fit is the 135 degree split point on cobalt steel. This geometry reduces walking on hard surfaces and the cobalt alloy resists heat during prolonged drilling, making it the correct choice for tougher alloys and stainless steel.
Standard Shank Installation
The bit fits any standard three-jaw chuck or quick-change adapter without extra hardware. The split point starts on contact so centre-punching is often unnecessary. The only common issue is premature wear if cutting fluid is omitted when drilling deep holes in hard metal.

Questions about this item
How does the 135-degree split point perform in a real machine?
The 135-degree split point centers itself on contact and reduces walking, so the bit starts cutting accurately in metal without a centre punch.
What does the cobalt construction cap in practice?
Cobalt steel resists heat and wear better than standard high-speed steel, letting the bit hold its edge longer when drilling hard alloys.
What does the jobber length need to fit or mount?
The jobber-length shank fits any standard three-jaw drill chuck that accepts a 1/4-inch diameter shank.
