Home improvement drilling tools aimed at accurate metalwork, promising reduced wandering and cleaner holes. Tradespeople and keen DIYers gain confidence from reliable starts and consistent results with Makita HSS-GS Drill Bit. Is this the workshop bit that will earn a regular place in the kit?

⚡ At a Glance
  • Cutting Quality: Split point and a 135 degree tip give a fast bite and steady drilling action in metal
  • Best for: Construction, sheet metal work and metal workshops needing reliable metal drilling
  • Not ideal for: Timber, masonry or purpose-specific materials that need specialised bits

High-speed steel construction with a split point reduces wandering at drill start. Suitable for both ferrous and non-ferrous metals in workshop and site environments.


Accurate Starts – Thanks to Split Point and 135° Tip

Split point geometry combines a sharper central tip with secondary cutting lips, while the 135° angle lowers the effective cutting pressure at the tip. The result is a quicker bite and less tendency to skate across the material surface.

Quicker hole initiation reduces the need for pilot marks or centre punches and keeps hole placement accurate. Less rework and fewer slipped starts on metal surfaces.

Secure Chuck Grip – With Straight and Three-Flat Shank Options

Straight shanks are used for tip diameters up to 13mm, while larger tips use a 13mm shank with three flat faces to mate with drill chucks. The three-flat profile increases contact area and resists rotational slip under torque.

More positive clamping cuts down on bit slippage during demanding jobs and improves safety. Compatible with standard chucks used on-site and in workshops.

Versatile Metal Cutting – With HSS Material Suitable for Various Metals

High-speed steel construction tolerates the heat generated during metal drilling and maintains edge integrity on both ferrous and non-ferrous metals. The material balance favours durability without specialised coatings noted.

Useful across a wide range of metalwork tasks, from sheet metal to structural sections. Reduces the need to swap bits when moving between different metal types.

✨ The 4 Key Reasons for Makita HSS-GS Drill Bit
  1. Split point tip - Faster bite, minimises drill wandering for precise hole placement
  2. 135° point angle - Flatter tip yields cleaner holes and longer bit life
  3. Three-flat shank - Secure grip in chucks, reduces slip during high torque drilling
  4. HSS construction - Handles ferrous and non-ferrous metals with reliable wear resistance

❓ Frequently Asked Questions

Q: What materials can the drill bit handle?

A: Suitable for both ferrous and non-ferrous metals, making it useful across common metalworking tasks.

Q: How does the shank design affect compatibility with drill chucks?

A: Tip diameters up to 13mm use a straight shank while larger tips use a 13mm shank with three flat faces to prevent chuck slippage.

Q: Does the tip design reduce slipping when starting a hole?

A: The split point combined with a 135 degree angle reduces side slipping at the start of drilling, improving bite and accuracy.

🏆 Our Verdict

The Makita HSS-GS Drill Bit suits tradespeople and DIYers who need reliable metal drilling performance. Split point geometry and HSS construction give accurate starts and material versatility as its standout strengths. While higher-quality bits can cost more than basic economy options, the durability and consistent results deliver better long-term value for workshop use.
