Metric Tap and Drill Bit Size Table
| Tap | Metric Drill | US Drill |
|---|---|---|
| 5mm x 0.8 | 4.3mm | – |
| 6mm x 1.0 | 5.2mm | – |
| 7mm x 1.0 | 6.1mm | 15/64″ |
| 8mm x 1.25 | 6.9mm | 17/64″ |
How do you calculate metric tap drill size?
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.
What size is a 1/4 drill bit in MM?
| Drill Bit Hole Diameters | ||
|---|---|---|
| Metric Size | Fractional Size | |
| 7 mm | .2756 | 1/4 |
| 8 mm | .3150 | 17/64 |
| 9 mm | .3543 | 9/32 |
How do you read a tap size?
Example: 1/4 – 20NC The 1/4 represents the diameter of the thread in inches. The 20 represents the number of threads per inch or TPI. Standard taps are either standard coarse series threads NC (1/4-20), fine series threads NF (1/4-28) or extra fine series NEF (1/4-32).
What does M10x1 5 mean?
Understanding Inch & Metric Thread Callouts For example, an M10x1. 5 (coarse) thread has a 1.5mm pitch, while an M10x1. 25 (fine) thread has a 1.25mm pitch. To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads.
What is the drill size for M10 tap?
| Tap size | Basic major dia (mm) | Drill size (mm) |
|---|---|---|
| M8 x 1 | 8mm | 7mm |
| M10 x 1.5 | 10mm | 8,5mm |
| M10 x 1.25 | 10mm | 8,8mm |
| M12 x 1.75 | 12mm | 10,2mm |
What size drill bit do I need for a M10 bolt?
We use a Fischer type M10 shield anchor. These are specified using a high-grade steel with a corrosion resistant zinc plated finish. The shield requires a 16mm hole to be drilled that is dust and debris free.
Is a 1/4 drill bit 6mm?
6mm Drill Bit (~1/4″)
Is 3/8 drill bit the same as 10mm?
Yes, a 10mm hanger will physically fit on a 3/8″ bolt. 3/8″ = 9.525mm I don’t see any problem with that at all. Just don’t apply that thinking to drill bit diameters and bolt sizes! No mismatching of bolts and holes allowed.
What is metric tap?
Metric sizes are referred to as thread pitch. Chamfers are the length of the tapering threads at the front of the tap. Both the chamfered portion of the tap and the first full thread beyond the chamfer produce the finished thread of the part.
