## Summary description

Proline 77185 is a single metal drill bit with a diameter of 18.5 mm and overall length 198 mm.

Supplied as one piece, it is intended for workshop, construction, and repair applications.

## Long description

Proline 77185 is a single HSS metal drill bit with an 18.5 mm diameter and an overall length of 198 mm, intended for drilling steel and other ferrous and non‑ferrous metals. The bit features a 135° point angle with chamfering adjustment to speed up center starting and reduce walking, and it is fully precision ground to ensure straightness and accurate hole geometry. Supplied as one piece in protective packaging, this drill bit is suitable for workshop, construction, and repair tasks that require a mid‑size diameter and reliable metal cutting performance.
Advantages
The drill bit is manufactured from refined high‑speed steel (HSS), which provides increased abrasion resistance, improved resilience and higher torsional strength compared with standard carbon steel bits. Fully ground flutes and cutting geometry deliver high precision, consistent hole diameter and better straightness, while the 135° point with chamfering adjustment shortens lead‑in time and reduces the need for repeated center punching. The single‑piece supply and protective tube packaging help keep the cutting edge intact until use.
Suitable for
 Drilling holes in structural and sheet metal
 Workshop and maintenance drilling tasks
 Construction site metalwork and repair jobs
 Machine and hand drilling where an 18.5 mm hole is required

How to use
Secure the workpiece and mark the drilling position; use a center punch if necessary to aid precise start. Fit the 18.5 mm drill bit into a compatible drill chuck and tighten securely. When drilling metal, use steady feed pressure and appropriate cutting speed for HSS bits—moderate speed for larger diameters—and apply cutting fluid to reduce heat and extend tool life. Withdraw the bit periodically to clear chips and avoid clogging. After completion, clean chips from the hole and inspect the edge for any burrs.
Usage recommendations
For best results with this Proline HSS drill bit, use suitable cutting fluid, moderate spindle speeds, and firm but controlled feed. Store the bit in its protective tube when not in use to preserve the ground cutting edges and ensure consistent drilling performance.
