(b) (1) (A) Except as provided in subparagraphs (B) and (C), on or before March 1, 2019, each schoolbus, school pupil activity bus, except school pupil activity buses described in paragraph (2), youth bus, and child care motor vehicle shall be equipped with an operational child safety alert system.

(a) On or before January 1, 2018, the department shall adopt regulations governing the specifications, installation, and use of child safety alert systems.

(C) Any entity other than a school district, county office of education, charter school, or private school that operates a schoolbus, school pupil activity bus, except school pupil activity buses described in paragraph (2), youth bus, or child care motor vehicle that is subject to the requirements of this section may submit documentation as specified in subparagraph (B) to the department. Upon providing this documentation, the entity shall have an additional six months, not to extend beyond September 1, 2019, to meet the requirements of this section.

Crystallume DCC tools are finding rapid acceptance among manufacturers of graphite electrodes for use in EDM operations because they last 10 to 30 times as long as carbide tools currently used. Increased tool liferesults in longer periods of unmanned machining. The machining speeds for Crystallume DCC tools can be increased 2 to 3 times over the speeds used with carbide tools to increase your productivity. These features combine to increase the utilization of your machine tools. Crystallume's Mold Maker and Extended Shank tools offer features specifically for electrode and mold manufacturing. The Mold Maker tools have a 5 times diameter flute length with an extended shank. The big difference is the tolerance of the tools. With a cutting diameter up to 1/8" and 3mm the tolerance is +0.0000/-0.0005 and for tools larger than this, the tolerance is +0.0000/-0.0010. All shanks are held to a tolerance of -0.0001/-0.0003 to assure consistent and concentric gripping in shrink-fit holders. Mold Maker tools are available in sizes from 1/64" to 1/2" and from .5mm to 6mm in diameter. Tools below 1/4" and 6mm are available with and without extended reach. Crystallume Mold Maker tools are the most precise diamond coated tools available. The Extended Shank tools combine a short-flute length for maximum rigidity with a long shank for extended reach into deep cavities. When the extended reach is not required, you can choke up on the tool to make it extremely rigid as a stub tool. This is a great all-around tool that will become a workhorse in your shop.

(2) “Child care provider” has the same meaning as provided for “day care center” in Section 1596.76 of the Health and Safety Code.

The Extended Shank tools combine a short flute length for maximum rigidity with a long shank for reaching into deep cavities. When the extended shank is not required, you can choke up on the tool to make it extremely rigid as a stub tool.
