Chicago-Latrobe 49216 1/4 Inch HSS Drill Bit
This Chicago-Latrobe 49216 drill bit is a 1/4 inch high-speed steel cutting tool built for precision drilling. It features a 135 degree split point geometry and a black oxide finish. The right-hand cutting direction suits standard power tools. It is designed for screw machine and general-purpose applications.
For Metalworkers Needing Accurate Hole Starts
This bit suits machinists and maintenance technicians who require self-centring performance in metal. The split point reduces walking on hard surfaces. Buyers drilling deep holes requiring coolant delivery should look elsewhere because this bit is non-coolant-through. It also suits only right-hand rotation spindle setups.
135 Degree Split Point Geometry
The 135 degree split point is the specification that determines suitability for hard materials and quick engagement. It lowers the force needed to start a hole compared to shallower angles. The decimal equivalent is 0.2500 inches. No coolant-through channel is present in this design.

Questions about this item
Does the Chicago-Latrobe 49216 come as a single bit or a set, and is a drill chuck included?
The item is a single screw machine drill bit. A drill chuck is not included and must be supplied separately.
When should I choose the 1/4 inch 135 degree split point version over other sizes or point styles?
Choose this bit when you need a 0.2500 inch hole in steel or tough alloys and want the split point to start accurately without a centre punch.
What does the 135 degree split point mean for everyday drilling in a hand drill or press?
The 135 degree angle with split point lets the bit centre itself quickly and cut with less pressure in steel, reducing walking on hard surfaces.
