Hollow Point Drill Bits
Carbide-fluted Hollow Point Drill Bits Hollow point drill bits are used for drilling a wide variety of thin materials, such as layers of paper or fabric. When layered materials are drilled, the resulting waste flows through the hollow passageway of the drill bit. Unless the inside and outside surfaces of the tube are perfectly smooth, the rapid build-up of waste materials can produce considerable friction and heat, resulting in clogging of the tube and melting of the work piece. It is also more difficult to drill a straight, uniform diameter hole as the bit diameter decreases in size and its geometry changes.
Through years of precision machining experience, Philadelphia Carbide has perfected its techniques and successfully overcome the difficulties inherent in manufacturing hollow drill bits. Today, we are the only manufacturer in the United States capable of producing:
- Carbide-fluted hollow point drill bits featuring outside diameters from
0.062” to 0.625”
(custom sizes also available); lengths from 2” and up.
