Drill bit Makita HSS-TiN for metal 1/4" HEX shank 8.0 x 102 mm

Makita HSS-TiN metal drill bit with a 1/4" HEX shank, size 8.0 x 102 mm, is designed for drilling steel and non-ferrous metals. The bit is made of high-speed steel (HSS) and features a titanium nitride (TiN) coating to improve wear resistance and extend service life. The 1/4" hex shank ensures secure fitting in hand drills and impact drivers that accept hex shanks, providing stable torque transfer during drilling tasks.

Advantages

The HSS core provides toughness and heat resistance ideal for metalworking, while the TiN coating reduces friction and increases edge hardness, helping to maintain cutting performance over time. The 1/4" HEX shank allows quick bit changes and reliable retention in standard chucks and hex quick-change holders. The 8.0 mm diameter and 102 mm overall length give a balance between drilling capacity and reach for common metalworking operations.

Suitable for

• Drilling holes in steel, stainless steel thin sheets and non-ferrous metals (aluminium, copper, brass)
• Use with hand drills and impact drivers that accept 1/4" hex shanks
• Workshop repairs, fabrication and light construction metalwork
• Maintenance tasks requiring reliable, repeatable metal drilling

Key specifications

• Material: High-speed steel (HSS) with titanium nitride (TiN) coating
• Shank type: 1/4" hex shank for quick-change holders
• Diameter: 8.0 mm
• Overall length: 102 mm
• Application: Designed for metal drilling (steel and non-ferrous metals)

How to use

Secure the drill bit firmly in the chuck or hex quick-change holder of a hand drill or impact driver that accepts 1/4" hex shanks. Mark the drilling point and start at low speed to establish a center, then increase speed and apply steady, moderate pressure. Use cutting fluid or oil when drilling harder steels to reduce heat and prolong bit life. Clear chips regularly to prevent clogging and maintain cutting efficiency.

Usage recommendations

For best results, match drilling speed and feed to the material: use lower speeds for stainless steel and higher speeds for softer non-ferrous metals. Apply cutting fluid when working with harder steels, and avoid excessive side-loads that can cause premature wear or breakage.
