Send the Hold Well (豪力輝工業) part number together with your machine model and turret — Mongtec engineering maps it to the matching Mongtec article number at quotation. The check is free.
Hold Well manufactures in Daya District, Taichung City, Taiwan, the same city where Mongtec is headquartered, so for buyers already sourcing from Taiwan or nearby markets, lead-time differences between the two suppliers are typically driven by order volume and exact configuration rather than country-of-origin freight time.
Hold Well Industrial Co., Ltd. describes itself as having over 40 years of precision manufacturing experience, headquartered at No. 31, Alley 10, Lane 120, Section 2, Yahuan Rd., Daya District, Taichung City (source: https://www.holdwell.com.tw/, accessed 2026-07-10), and is distributed in North America through channel partners such as Techleader Tooling, Inc. of Orchard Park, NY (source: https://techleader.com/holdwell-tooling/, accessed 2026-07-10). Mongtec supports customers directly from Taiwan with engineering-verified spec sheets and quote turnaround for shops that need cross-reference support without navigating a distributor layer.
Hold Well's catalog spans a broad accessory range beyond angle heads and driven tool holders, including hydraulic vises, MC power vises, U-axis boring/facing heads, and turn-mill swing spindle heads, reflecting a full machine-shop-accessory manufacturer positioning. Mongtec's angle head and BMT/VDI driven tool holder lines target shops specifically sourcing tool-interface hardware, which can simplify vendor selection for buyers who don't need Hold Well's full workholding catalog alongside their tooling order.
Mongtec's BT40 angle head dimensions are drawn from Mongtec's internal engineering spec sheet, verified against the published product page at https://www.mongtec-tools.com/en-US/p296-bt30qer11 (accessed 2026-07-10). Hold Well's AHL-BT40-C8.65 model designation is confirmed via a product demonstration video published directly on Hold Well's own corporate site (accessed 2026-07-10); Hold Well's broader shank and collet range (BT30/BT40/BT50, CAT40/CAT50, SK30/40/50, HSK63, NT50, ER11-ER40) is confirmed via public secondary trade listings rather than a first-party numeric spec sheet this page could independently verify. Shops verifying an exact swap should request Hold Well's dimensional drawing for the AHL-BT40-C8.65 model directly and compare it against Mongtec's BT40 spec sheet before ordering.
If a Hold Well (豪力輝工業) unit on your machine is worn, damaged or discontinued, you do not need the original article number to replace it. Send the model number, the name plate photo, or the drawing of the angle head you run today — Mongtec engineering cross-references the mounting, coupling and output geometry and quotes a suitable Mongtec article, stating clearly which dimensions were confirmed. Repair of the existing unit is sometimes the better answer; where we see that, we say so.
Mongtec publishes this comparison so buyers can judge the swap themselves. It is not a claim that one brand is better than the other — the two are different companies with different ranges, and the right choice depends on the machine and the job.
Send it to info@mongtec.com or use the enquiry form. A drawing or a photo of the unit on the turret speeds this up; neither is required to start.
