Stock reamer
754.2 /33.9 mm
Separate stock contents from optional coverage
Choose the exact cutting and pilot contacts for the actual standard; do not buy from a general family claim.
What this choice changes
Stock machining contacts are different from optional capability
The HTR-1B combines head-tube reaming and facing in its documented stock configuration. The included 33.9 mm reamer is 754.2 and the 45 mm facer is 690. Reaming a bore and facing an end surface are separate contacts within the same system; a broad bottom-bracket family title does not mean every corresponding cutter is in the box.
The maker identifies four stock pilots as 762, 763, 765 and 766. Its stock scope faces EC29, EC30, EC34 and EC37 and reams EC34. Broader headset or press-fit bottom-bracket applications require the exact optional cutters/pilots. Match the actual standard, contact and approved machining operation before selecting the kit.
One selected-field detail remains uncertain: the description gives 33.8 mm for the third pilot, while a bullet gives 33.9 mm; the maker names 33.8 mm for part 765. The 33.9 mm reamer is a different part, not a reason to silently assign that value to the pilot. Confirm the supplied pilot when that contact is essential. Suitable cutting fluid is required and not established as included.

Keep the reamer and pilot distinct
33.9 mm identifies the stock reamer. The selected third-pilot figure needs separate confirmation.
Fit checks & limits
- Selected third-pilot 33.8/33.9 mm wording is unresolved at offer level; not an unqualified exact-fit filter.
- No universal frame material, press-fitBB standard or machining approval.
- No additional optional tooling or cutting fluid included by implication.
Questions before you choose
Does it include every cutter needed for press-fit bottom brackets?
No. Broader functions require the exact optional contacts; use the documented stock configuration to assess this offer.
Is facing the same operation as reaming?
No. The stock 45 mm facer works on the end surface; the 33.9 mm reamer is a different contact for the stated bore-machining scope. Choose the actual approved operation and matching pilot.
What should I check before buying for a specific headset?
Identify the standard, whether facing or reaming is authorized, and the exact stock or optional cutter/pilot required.
