Quick answer
The replacement drill set for the Revell 39064 hand drill includes two 0.7mm bits, two 1.0mm bits, and one 1.3mm bit. Use the 0.7mm for fine pilot holes, 1mm for standard plastic model parts, and 1.3mm for slightly larger hardware or alignment pins.
Why these three sizes cover most model building needs
Plastic model kits typically require small-diameter holes for parts alignment, antenna mounts, or adding aftermarket details. The set's 0.7mm bits handle delicate work where a 1mm hole would be too large, while the 1.3mm bit gives you room for metal wire or rod that needs a snug fit. The two 1mm bits are the most used size for standard sprue attachment points and pin-vise drilling.
If you only drill occasional holes, you might get by with a single bit size. But having duplicates of the 0.7mm and 1mm sizes means you can keep one sharp bit in the chuck and one as backup—useful because small bits can break if you apply too much side pressure.
Frequently asked questions
What sizes are included in the replacement drill set for Revell 39064?
The set includes two 0.7mm bits, two 1.0mm bits, and one 1.3mm bit.
Which drill bit size should I use for plastic model parts?
Use the 1.0mm bit for most standard holes, such as adding a pin to align two parts. Use the 0.7mm bit for very fine work like antenna holes or small detail parts. Use the 1.3mm bit when you need a slightly larger hole for brass rod or thicker wire. Match the bit size to the part's thickness: 0.7mm for delicate, 1mm for general, 1.3mm for heavier additions.
Can I use these bits with other hand drills or pin vises?
The bits have a standard 2.35mm (3/32 inch) shank, so they fit most hobby pin vises and hand drills, not just the Revell 39064. However, the set is specifically designed and recommended for the Revell 39064 to ensure proper chuck grip. Check your tool's collet size—most accept 2.35mm shanks, but always verify before buying.
How do I prevent the small drill bits from breaking?
Apply light, steady pressure and let the bit do the cutting. Avoid wobbling or forcing the drill sideways. Use a slow rotational speed and back the bit out frequently to clear plastic dust. If you feel resistance, stop and clear the hole rather than pushing harder.
