2-flute Carbide Medical / Slotting Drill Bits (DC2M8) - 1/8 in. (0.125 in. shank)
Overview
Think & Tinker 2-flute carbide medical / slotting drills are a different breed of tool. Originally designed for truing the bore of hypodermic needles, the flute geometry possesses many of the characteristics of an end-mill including a relatively thick core and heavier flute profiles. Being far more rigid that a conventional PCB drill, these bits are commonly used for "drill-milling" very narrow slots in electronic substrates or sharpening inside corners in inlay parts and pockets.
As with our standard drill bits, every tool is:
- 100% measured / optically inspected to insure that EVERY tool meets, or exceeds, our published specifications
- available with depth rings precisely positioned to ±0.004 in. (0.10mm), virtually eliminating the need for resetting Z-axis zero in many applications
- made from premium grade submicrograin tungsten carbide (HRa: 93, TRS: 4.0GPa ) with a bonded stainless steel shank
Specifications
- Geometry - 2 flute, 1/8in. (3.18 mm) shank, drill point

Benefits
- Thick core and controlled aspect ratio reduces delflection in slotting operations
- Shallow point angle minimizes backside breakout burring
- Tip geometry insures efficient swarf removal
- Tip geometry and back tapered flutes virtually eliminate top surface burr formation
- Four facet drill point minimizes grabbing and lifting of work-piece
Applications
- Slotting printed circuit boards and composite substrates
- Drilling stainless steels, ferrous alloys, exotic metals metals
- Suture pockets
- Fiber optic ferrules
- Fuel injection ports
- Gold, silver, and platinum beads
Tutorials
- Minimizing system runout with proper spindle maintenance
- Getting ready to work with microtools for the first time
