HSS drill bit KREATOR KRT010119 — 8.5 mm diameter, 117 mm length

HSS drill bit KREATOR KRT010119 — 8.5 mm diameter, 117 mm length is a general-purpose high-speed steel (HSS) twist drill designed for routine drilling tasks in metal, wood and plastic. The bit's 8.5 mm cutting diameter and 117 mm overall length make it suitable for through-holes and medium-depth drilling. Manufactured with HSS material, this drill bit balances wear resistance and toughness to provide consistent cutting performance when used in standard drill chucks and hand-held or bench drills.

Advantages

The HSS construction offers good heat resistance and edge retention during intermittent drilling in ferrous and non-ferrous metals, while also remaining effective in wood and plastic. The 8.5 mm diameter provides a common size for fastening and clearance holes, and the 117 mm length gives extra reach compared with short bits. Ground flutes and a standard point angle deliver reliable chip evacuation and straightforward centring for typical workshop and DIY applications.

Suitable for

• Drilling holes in mild steel, aluminium and other non-hardened metals
• Creating clearance and pilot holes in wood
• Drilling plastic components and panels
• General repair, fabrication and maintenance jobs
• Use with standard corded or cordless drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 8.5 mm
• Overall length: 117 mm
• Tip type: standard twist point for general-purpose drilling
• Shank: straight round shank for standard drill chucks
• Suitable materials: metal, wood, plastic

How to use

Secure the drill bit firmly in a compatible drill chuck, tightening the chuck jaws to prevent slippage. Select an appropriate rotational speed for the material — lower speeds for steel, medium for aluminium, and higher speeds for wood and plastics. Use cutting fluid or light lubrication when drilling metals to reduce heat and extend bit life. Apply steady, even pressure and allow the bit to remove chips naturally; retract occasionally in deep holes to clear chips and prevent clogging.

Usage recommendations

Ensure the drill and bit are aligned with the drilling axis before starting. For best results in metals, pre-mark the hole with a centre punch to improve accuracy. Replace the bit if the cutting edges become dull or chipped; regrinding is possible for HSS bits but requires suitable equipment. Store the bit in a dry place to avoid corrosion.
