## Long description

Proline 77710 is a single high-speed steel (HSS) metal drill bit with an 11 mm cutting diameter and a total length of 365 mm. Intended for drilling metal, this extra-long solid drill bit offers extended reach for workpieces that require deep or hard-to-access holes. The bit is fully ground to ensure accurate and straight holes and is supplied as a single piece for use in compatible drill chucks and holders.
Advantages
The drill bit features a 135° point angle with a chamfering adjustment that enables quick penetration and reduces the need for repeated marking. Fully ground flutes provide improved accuracy and rectilinearity of holes, making the tool suitable for use with drill bushes. Manufactured from refined high-quality HSS, the bit offers durability and consistent cutting performance in steel, non-ferrous metals and plastics.
Suitable for
 Drilling through steel plates and structural steel components
 Creating 11 mm holes in non-ferrous metals such as aluminium and brass
 Drilling deep or recessed holes where extra length (365 mm) is required
 Workshop, maintenance and construction tasks requiring precise straight holes

How to use
Install the drill bit securely in a compatible chuck or holder ensuring proper clamping of the shank. Align the drill at the intended mark and start drilling at a low speed to establish the hole, then increase speed as appropriate for the material being drilled. Use cutting fluid when drilling steel or harder metals to reduce heat and prolong tool life. Maintain steady feed pressure and clear chips periodically to avoid clogging along the extended flute length.
Usage recommendations
For best results, use the Proline 11 mm × 365 mm drill bit with drill bushes when precision and rectilinearity are required. Apply appropriate lubrication for metal drilling, secure workpieces firmly, and avoid excessive lateral forces to preserve cutting geometry and prevent breakage of the extra-long bit.
