Here's what we know about it:
The main difference between the Starrett micrometers T230RL and T230FL lies in their thimble mechanism:
1. T230RL:
- Features a ratchet stop mechanism
- Includes a lock nut
- Provides uniform pressure and quicker adjustment
2. T230FL:
- Equipped with a friction thimble
- Also includes a lock nut
- Offers smooth friction for uniform pressure
Both micrometers share the following characteristics:
- 0-1" (0-25mm) measurement range
- .0001" graduation for high precision
- Spindle and anvil sized at .235" (6mm) to reach places most micrometers cannot
- Quick-reading figures with every thousandth numbered on inch tools
- Designed for use by skilled workmen worldwide
The choice between the T230RL and T230FL depends on the user's preference for either the ratchet stop mechanism (T230RL) or the friction thimble (T230FL) for controlling measurement pressure and adjustment speed.
